11 Years Old - DeconstructingTime Blog

This Blog
DeconstructingTime
Is 11 Years Old

This post is an overview
of what was accomplished
during those 11 years


Eleven years ago, in December 2012, I began this blog to investigate and examine the human experience and understanding of time.

"Human statue from Ain Ghazal city, in the outskirts of Amman, Jordan. Pre-pottery Neolithic period B, 8th millennium BCE."
The latest dating indicates that this figure was made 3000 years before the beginning of the Sumerian civilization, This means that basket weaving technology with reeds was quite advanced by the Neolithic Pre-Pottery B time period. (Ben-Nissan, Advances in Calcium Phosphate Biomaterials)



THE BASIC IDEA

The basic idea for this blog is quite simple. It is now clear that our sense of time evolved from the immediacy of animal existence to our modern sense of linear time with a past, present, future, and duration. But it is my contention that this may have taken millions of years to evolve and that it went through a number of stages.

In addition, I think that early and late hominins, i.e., pre-Homo sapiens, were much smarter and cleverer than previously thought. And further, that early Homo sapiens were much smarter than previously thought. For example, I think that many Neolithic cultures were technologically advanced.

One of the principal barriers to understanding earlier people has been our modern point of view. We need to imagine the past from the point of view of a past culture and free ourselves from modern assumptions.

WHY IS THIS IMPORTANT?

Our sense of time is a key reason that we became the dominant species on the planet with our ability to plan and design. So we need to understand it. Furthermore, our understanding of time is critical as we deal with global warming. For example, if it happens quickly we are in deep trouble; if it happens slowly we can probably plan and adjust.

SOME STATISTICS

I have written over 120 fully illustrated blog-articles which are often 3000 - 7000 words long with footnotes, links to supporting documents, and notes about the research. I spent at least 40 hours writing each blog. In total all of these blogs are equivalent to more than 1000 pages.

Currently, this site averages 3700 views a month and on the three academic sites, where these articles are reprinted, another 1500 views and downloads per month are indicated. On the academic site, Academia.edu, my work is usually in the top 1% of papers viewed. On that same site, I have more than 1080 followers. Altogether articles from this blog and those that have been reprinted on the academic sites have been viewed and downloaded more than 300,000 times.


WHAT WAS DISCUSSED AND DISCOVERED

It has been a wild ride. Never did I imagine that I would end up writing articles about the Lower, Middle, and Upper Paleolithic, the Neolithic, Mesopotamia and Egypt, the geocentric theory of the Earth, the brain, the evolution of language, basket weaving, and right angle construction.

NEW DISCOVERIES
To my surprise and delight recent discoveries of artifacts, new dating, and microscopic direct evidence have supported many of my ideas in this blog. 

To summarize the new findings: direct evidence of rope made by Neanderthals was found using microscopic techniques, new dating showed that sophisticated baskets were made by hunter-gatherers which for a hundred years had been dismissed as impossible, and half a million years ago pre-Homo sapiens hominins made a sophisticated wooden structure with a notched right angle part which again was thought to be impossible. All three of these discoveries were consistent with my ideas and predictions of early hominin technology. All three indicate significant cognitive abilities which required planning and a sense of time.

THE HUMAN BRAIN
I was one of the first people to write about the prefrontal cortex (PFC) and how it may be a key part of our brain that gives us a sense of time, an actual sense like smell or taste. The PFC appears, for example, to allow basic thinking about time and the future such as considering several chess moves. 




DID EARLY HUMANS LEARN COMPLEX WEAVING FROM WEAVERBIRDS?
I believe I was the first researcher to suggest the following. I was able to show that early hominins, more than a million years ago, lived in close association with weaverbirds who made complex intricate tightly woven nests that looked like containers. I can say this because fossil skeletons of weaverbirds were found in the same layer as Oldowan stone tools at Olduvai Gorge. Also in my research, I found that virtually all anthropologists believe early hominins lived around baobab trees, ate their fruit, and often found honey there. And weaverbirds also made their nests in baobab trees.
Early hominins would have been able to observe these birds making nests which often took more than a day and the birds used a variety of knots and weaving techniques. Abandoned nests fell to the ground where hominins could have examined them closely. So I believe it is possible that early hominins learned complex basket weaving from these birds.

RIGHT-ANGLE STRUCTURES
I wrote two articles about the importance of right-angle construction and how it was a key element in structural design from small baskets to large structures. My hypothesis is that this structural idea was already part of early hominin thinking and engineering about 300,000 years ago. 

As I said earlier, a structure made half a million years ago by pre-Homo sapiens was recently identified. It had clearly used a notched right-angle piece of wood as part of its design. This finding has added support to my hypothesis.

BASKET WEAVING (WOVEN-FIBER TECHNOLOGY) DURING THE PALEOLITHIC ERA
In September 2019, I wrote the following article: 


I made the point that considerable indirect evidence suggests that basket weaving and related weaving existed in the Paleolithic era, especially the Upper Paleolithic, and this technology was capable of making a wide variety of items from small baskets to houses and boats. While indirect evidence of impressions in clay proved that basket weaving existed in the Upper Paleolithic era, there was no direct evidence. 

But now in a report dated November 2023, new radiocarbon dating of complete baskets found in a cave in Spain has shown that hunter-gatherers had mastered this technology contrary to assumptions that had prevailed for over 100 years which maintained this was impossible. 

And more, the implications of this discovery are large. If these societies could make these well-woven baskets, they probably could have made many other things with woven-fiber technology such as small boats, temporary houses, mats, and a variety of food-related items such as plates, bowls, water-carrying baskets both large and small and even baskets for cooking (really). What I just mentioned are items that hunter-gatherer Native American Indians were able to make with weaving technology.

This means the Upper Paleolithic cultures might have been much more advanced and developed than previously thought. And this is what my article suggested.

A PRECISE NEOLITHIC INSTRUMENT AT NEWGRANGE
I wrote a detailed study of the Newgrange passage tomb in Ireland. It is now proven that, around the time of the winter solstice, light comes directly down the passageway and only around that time. But I have suggested it could be taken one step further. I believe the configuration could determine the actual day of the solstice in real-time, an idea that others have suggested but which I have covered in much more detail. Furthermore, if I am right, the Greeks and Romans, 2500 years later, could not determine the day of the solstice in real-time according to my research. So this would mean that the science of the Neolithic culture at Newgrange was more advanced than Greek and Roman science in some respects.

The very slight change in the sun's position at the time of the winter solstice combined with atmospheric conditions has made it virtually impossible to pinpoint the actual day of the solstice in real-time. However, I believe that the Neolithic scientists at Newgrange found a way to do just that. I have been a professional photographer for 30 years which often involved lighting. My art photographs, which are different from my commercial work, are often pictures of landscapes with low-angled lighting or abstracts with unusual lighting. This means I understand how light works and how a slight change in an angle from a light source can make a difference. For example, the shadows can be different. 

So I am reasonably sure that a slight change in the sun's angle around the time of the winter solstice could be clear when viewed in the passageway at Newgrange. This is because in many ways the passageway at Newgrange behaves like a scientific instrument that magnifies the sun's rays. I believe this magnification reveals the difference between the day of the solstice and the days before and after. I feel this hypothesis could be and should be scientifically tested which I have advocated. With the new science of photogrammetry which can create a precise interactive digital model, this should not be hard to do. The difficult part for a simulation would be to make sure the sun's rays were entering the passageway at just the right angles.



This grass house (mudhif) was built entirely out of reeds, including the rope and mats. Many archaeologists believe this basic design was older than the first Mesopotamian cities and these types of buildings housed many people after the Sumerian civilizations had risen.
"Iraq's Marsh Arabs use reeds to build vaulted reception halls called mudhifs, such as this one at Albu Hamrah near the ancient Sumerian archaeological site of Lagash."

EARLY CIVILIZATIONS AND THE REED INDUSTRY
I offer substantial evidence (such as cuneiform receipts and about a hundred weaving-related words) that Mesopotamia had a large critical reed industry which has not been identified by other researchers. Plentiful reeds were used extensively throughout these societies. Sophisticated reed construction was used to make a variety of large and small boats, large and small buildings, a wide variety of baskets for domestic or commercial use, and all-purpose mats.

I did the research to establish this because I think it is possible that the grid structure of reed baskets was a model for Mesopotamian astronomy which divided the night sky into vertical and horizontal sections. Babylonian scientists created our modern system of hours, minutes, and seconds which we still use today. We even use the same math of sixty minutes to an hour and 60 seconds to a minute as the Mesopotamians. 



Gears in a pocket watch that use Ptolemy's geometry.

THE GEOCENTRIC SOLAR SYSTEM AND OUR MODERN MACHINE AGE
My last possible "proof" brings my ideas in this blog up to today. It involves the discredited Earth-centered astronomy, known as geocentric astronomy, of the Greek astronomer Ptolemy. His system was used to create a yearly calendar, but over time it became clear that the calendar was off. This led to the more accurate sun-centered, heliocentric system, that we use today. Once this older system had been discarded, many knowledgeable people, such as my college history teacher, made fun of its epicycles or wheels within wheels, considering them absurd and cumbersome. 

But they had missed a basic point. While the calendar was off, it was only off by one day every hundred years! This meant that the basic geometry and math were quite accurate. They were so accurate that starting around 1400 CE, many medieval clocks were made based on this system and its "absurd" gearing -- and they worked very well. Some are still working today after about 600 years.
 
Clocks based on the Ptolemaic geometry were constructed up to the time of the Industrial Revolution which used the same geocentric gearing for the invention of numerous machines. Today this engineering of gears and gearing is very much a part of the modern world. 

But don't take my word for it. As one of the acknowledged experts on the subject of clocks said, Clocks were the "key machine of the modern industrial age."
Strandh, Sigvard (1979). A History of the Machine.

When the industrial age began expert clockmakers were in high demand. This is because many machines were like a clock that must operate in a specific order and then repeat.


OTHER IMPORTANT IDEAS

I believe the immediacy of time that animals experience changed slowly during the Paleolithic era. It developed into an understanding that some things such as processes required a sense of linear time. A process must be planned and executed in a certain order, for example, and the end result must be imagined at the start of the process. Next, in the Neolithic era, I believe that time was seen as cyclical with repeating yearly seasons. However, within the cyclical seasons, long-term yearly linear planning could be implemented. So preparing ground for planting, planting, harvesting, and storing grain would have required a linear way of thinking but within a world that was believed to be cyclical. Finally, linear time became the principal concept that we use today. Time is seen as a commodity that can be managed and planned. "Time is money," as the saying goes.

LANGUAGE
A hunter-gatherer tribe in the Amazon, the Piraha, uses a language that speaks of time in immediate terms. This could be an example of an earlier culture which works with time as being immediate.

BASKETRY AND WOVEN-FIBER TECHNOLOGY
I believe that basket weaving or woven-fiber technology was a plant material technology that existed along with stone tool-making for perhaps millions of years. Furthermore, I think that baskets and other woven-fiber items should be considered tools, although, for some odd reason, they have not been given the status of 'tools' in the past. I also think that weaving with its regular grid-like patterns may have become one of the models for time. 


MODERN ASSUMPTIONS, BIASES, AND MISCONCEPTIONS

In my research, it became clear that one of the biggest obstacles to discovering the truth about early technologies and early societies was our modern point of view. In particular, I found that the art of basket weaving had been subjected to a range of incorrect assumptions that prevented it from being given the status it deserved. Here are some of those mistakes.



"The [basket that this] grandmother is weaving about herself
is to be used as a store for grains and vegetables."
This storage basket is very similar to an early Neolithic basket that was just found.
This is a colorized B&W photo from 
American Indians: first families of the Southwest by Huckel.
"Relatively few tribes of American Indians understood pottery, except in the crudest form. As for basketry, it may be said that every Indian from the land of the Esquimaux down through Mexico was a basket weaver." Quote from the above.

6 MISCONCEPTIONS ABOUT THE IMPORTANCE OF BASKETRY
#1. A basket is a tool! For some odd reason, basketry has not been valued for its functions and usefulness and has rarely been given the status of a tool. Yet even simple container baskets fit the definition of a tool and other more complex products made with a woven-fiber technology do as well.

#2. It was assumed for over 100 years that basket weaving must have begun in the Neolithic era because it was labor-intensive. It was assumed that Paleolithic people did not have the time or the skill to make baskets while Neolithic people did. However recent studies showed that hunter-gatherers have more free time and horticultural farmers less free time.

#3. It was assumed that pottery was an advance over basket weaving and that cultures that used pottery were more advanced than those that made baskets. But basketry was quite sophisticated when it became fully developed and it was more appropriate for nomadic societies because it was light, strong, and could be made from local plants in just about any environment. In other words, it worked better for nomadic people and may have been a sophisticated technology.

#4. The huge variety of items that could be made with woven-fiber technology was not recognized. I put together a list of things that could be made, from sandals to huge buildings and sea-going reed ships, to show the versatility of this technology. It included clothing, roofs for houses, fences, heavy-duty baskets for dredging canals, and even levy construction. I believe this versatility made it a key technology for Neolithic societies and the later Egyptian and Mesopotamian civilizations as well. I believe these civilizations could not have functioned without it.

#5. In the 1800s and most of the 1900s, the work of women was not valued. So when anthropologists looked at the basketry of Native American Indians in North America it was often seen as "women's work." Many of the best baskets and woven-fiber items WERE made by women but their skill was highly valued by Indian men who understood the complexity of the craft. These baskets were so well made that many of them lasted for generations and were passed down as family treasures.

#6. We all know the joke about the incredibly easy college course, "Underwater Basket Weaving." This joke reflects the lack of respect that basketry has received. As a result, I have suggested that the technology be renamed "woven-fiber technology" since basket weaving "can't get no respect!"

ONE MORE EXAMPLE OF A MODERN BIAS -- NEWGRANGE
Archaeologists knew about the Newgrange passage tomb for over 250 years but assumed that it was just another crude stone Neolithic building. Because it looked crude to their eyes they were incapable of understanding that it was built with great precision not only in its construction but in its orientation as it was exactly placed to capture the sunrise around the time of the winter solstice -- a fact which today is no longer in dispute. 


CONCLUSION

I hope I have added to the conversation about the importance of time and added to an understanding of how we humans developed a sense of time and how we perceive and use time. I feel that this is the most important thing I could do: to contribute to the conversation and to ask good questions.

At the same time, I did try to make a complete narrative from the earliest beginnings of human-like creatures right up to today. I have written at least one article about each important time period. So I have made an attempt to tell a full story which you may or may not agree with but at least it is an attempt at such a story.

And in the future, I will try to find evidence or ideas that will fill gaps in my narrative.

Discovery: Prehistoric Baskets By Nomadic Hunter-Gatherers


A MAJOR DISCOVERY OF DIRECT EVIDENCE:
Well-Preserved Baskets Are Found To Be 
2000 Years Older Than Previously Thought
&
The Ideas of Rick Doble who predicted this


New radiocarbon dating has determined that prehistoric artifacts, based on a basket weaving technology, found in the 'Bat Cave' in Spain (Cueva de los Murciélagos, Albuñol, Granada) are 2,000 years older than previously believed. The oldest are about 8,500 BP and related to early nomadic Holocene hunter-gatherers in Europe.

Detail of above.


Detail of above.


SUMMARY OF THE SIGNIFICANCE OF THIS DISCOVERY
-- This new dating means that a kind of threshold has been crossed; it means that the oldest artifacts were made by nomadic hunter-gatherers and not Neolithic people as had been previously thought.
-- Until recently it was assumed that basket weaving and woven-fiber technology began in the sedentary Neolithic time period and that this kind of advanced technology would not have been possible for nomadic hunter-gatherers.
-- The sophistication of the oldest baskets also indicates that this technology had been developing in the Paleolithic era for a long time, as it would taken many years for this kind of craftsmanship to develop.
-- It also means that at the beginning of the Neolithic era, the technology was already quite sophisticated. The Neolithic people inherited a woven-fiber technology that had been well developed by nomadic hunter-gatherers and which they could add to or improve upon and which was also crucial for the establishment of the Neolithic way of life.
-- In both cases, it shows considerable skill and good designs.
-- Having direct evidence of complete well-preserved artifacts means that this technology can now be studied in great detail which will also reveal a good deal about the abilities of nomadic hunter-gatherers.
 
“The quality and technological complexity of the basketry makes us question the simplistic assumptions we have about human communities prior to the arrival of agriculture in Southern Europe,” the study's leader, Francisco Martínez Sevilla, said and was quoted in the original SCIENCE ADVANCE article.

A complex and skilled process:
"The ancient humans crushed the grass to make twine to braid baskets, bags and sandals. The grass had to be dried for 20 to 30 days before it was rehydrated for 24 hours to make it pliable — a complex and skilled process."


THE DISCOVERY IN DETAIL

Anthropologists have known about these various woven-fiber items for decades but they were believed to be Neolithic. Now, however, this new dating shows that the oldest items were made by nomadic hunter-gatherers before the Neolithic era and are direct evidence of that fact. These items are well made and show a highly advanced technology.

This is extremely important because it places the time of the production of sophisticated basket weaving and woven-fiber technology long before the Neolithic era. The discovery of an advanced technology means that it usually came from a technology that had been developing for many years prior. This indicates that an earlier version was probably available to nomadic hunter-gatherers and suggests that well-made items could have been designed and created tens of thousands of years earlier than previously thought. 

This discovery changes our understanding of the time period before the Neolithic era, e.g., the Upper Paleolithic and also the Mesolithic period just before the Neolithic. Prior to this, only indirect evidence had been found in the form of basket weaving impressions in small bits of clay which were even much older. This current find provides direct evidence of well-preserved complete intact artifacts which greatly supports the earlier indirect evidence.

This discovery applies to the largest and most comprehensive group of baskets found so far that are intact and from the nomadic hunter-gatherer era. This means that the method of weaving and of processing the fibers, and the sturdiness of the design can all be studied in detail. Most of these baskets used fibers from the esparto plant which was highly valued for its many uses and properties. 

This technology was probably valued by nomadic hunter-gatherers because woven fiber items were light, strong, and durable and could be made in a wide variety of shapes and sizes for a wide variety of purposes including large burden baskets, containers, cooking baskets, bowls, plates, and very large and small water carrying baskets. They could also be designed to store grain for long periods of time. 

In this recent discovery complete well-made woven-fiber containers, baskets, bowls, plates, and shoes are some of the artifacts that were found in this dry cave along with fragments of cloth and mats. Normally fiber-based items decay quickly but in this case, the cave was quite dry and preserved these items. This find is rare and provides major evidence that usually is lost.

Furthermore, the discovery shows that at the very beginning of the Neolithic era this technology was already highly advanced. It is my belief that because it had been so well developed it provided Neolithic cultures with the early necessary tools for their sedentary way of life to take hold. 

While the Neolithic is famous for the invention of pottery and the domestication of animals, these only came during the last third of the Neolithic era. Basket weaving (woven-fiber) technology was needed for thousands of years before pottery was perfected and long before pack animals were domesticated. So woven-fiber technology was a crucial key industry. 

Furthermore, pack animals still required baskets to carry loads and light strong durable baskets were still essential for other work. Woven-fiber technology continued to advance so, for example, when reed fibers were combined with naturally occurring bitumen, small boats, and large sea-faring ships were built in the Persian Gulf area as well as large and smaller 'grass' (reed) buildings. 


SUPPORT FOR DECONSTRUCTINGTIME'S IDEAS

I have written several full-length articles that predicted and supported the idea that nomadic hunter-gatherers had a fully developed highly advanced woven-fiber technology that was both versatile and complex. This idea goes against the previously commonly held belief that hunter-gatherers were not capable of such a technology.

I am especially pleased about this find of direct evidence because it confirms many of my ideas and predictions that I have been suggesting for the last four years in this blog. Furthermore, it fits very nicely into my ideas for a revised much longer timeline of how woven-fiber technology developed. Until recently, researchers believed that basketry had begun in the Neolithic era. Now with this and other evidence, it appears that the development could have happened over tens of thousands of years or more. And this, again, is what I have suggested and predicted. Another recent discovery, that I reported in the last blog-article, confirms that early hominins had sophisticated plant material skills and even engineering skills half a million years ago. 


OTHER ANTHROPOLOGISTS AND ARCHAEOLOGISTS HAVE OFFERED SIMILAR IDEAS BEFORE I DID 

I need to point out that several other anthropologists and archaeologists, years ago,  offered the same idea of basketry being made in the Upper Paleolithic and before the Neolithic  Most of them have many more credentials than I do. 

Nevertheless, I feel that I have added something significant to this discussion. I believe that woven-fiber technology was a key technology beginning perhaps at the same time as Oldowan or Acheulean stone tools. I also believe that baskets and woven-fiber items are tools and need to be thought of as such. My theory about basket weaving technology goes back hundreds of thousands of years so it is important to me to place each step at the right point in time, as much as possible. 

The sophistication of these recently dated nomadic hunter-gatherer artifacts suggests that the technology was very old and that basket technology worked well with nomadic people who needed tools that were strong, light, and portable and that could be made from local plants. Furthermore, I believe that Neolithic societies inherited a fully developed technology from the Paleolithic era and did not invent it as was previously thought. Then the Neolithic cultures passed their even more developed technology down to the great emerging civilizations such as those in Mesopotamia that I believe had a large reed and fiber industry that was critical for the rise of their civilizations.

DID THE EMERGING NEOLITHIC WAY OF LIFE DEPEND ON BASKET WEAVING TECHNOLOGY DEVELOPED EARLIER BY HUNTER-GATHERERS?
I BELIEVE IT DID.

The Neolithic way of life may have depended on the sophisticated advanced development of basket weaving technology (what I have renamed woven-fiber technology) because it could create a wide variety of well-made light-weight rugged items that were necessary for the Neolithic lifestyle of planting, harvesting, and storing. I believe all of these essential technologies were initially accomplished with basket weaving skills. 


See my article where I explain the skills of nomadic hunter-gatherers and how these skills were probably passed on to Neolithic cultures.

Pre-Pottery Neolithic Basket Weaving

I argue that for the first two-thirds of the Neolithic era, basketry was the key technology that allowed the Neolithic system to take hold. It was only in the last third of the Neolithic era (approx.) that domestication of animals and the use of pack animals replaced people carrying harvested crops in large 'burden' baskets on their backs, that pottery was developed, and that fabric for clothing and other uses, such as sacks, was perfected. And while these new technologies gave the Neolithic societies a major boost, they did not replace the use of woven-fiber technology which continued to be widely used for many different purposes such as the manufacture of small and large boats made of reeds and fibers.

CONCLUSION

While we can be delighted that this recent direct evidence has been found, unfortunately, the central problem still remains, which is that while natural fibers and wood probably were the largest materials used by early humans as all researchers agree, almost all evidence has decayed and thus is very hard to find. But now, at least, we are beginning to know what to look for

AFTERWORD

ESPARTO WOVEN-FIBER ARTIFACTS
From an earlier DeconstructingTime blog-article
before the discovery that these artifacts were 2000 years older.


Just how versatile was this technology? What kind of products could it provide? Woven-fiber technology was dependent on the plants that grew wild locally. So reeds were plentiful and versatile around Mesopotamia, papyrus was widely used in Lower Egypt, and in Spain and in North Africa the esparto plant was valued for its many uses.

Fortunately, in the case of esparto, we have direct evidence since many baskets, shoes, and mats have survived intact. The existence of these items also shows that basketry and weaving technologies were being widely used in the Neolithic and earlier. 

 
The following is quoted from:
Traditional Craft Techniques of Esparto Grass (Stipa tenacissima L.) in Spain
"Numerous archaeological artifacts and remains of esparto basketry have been discovered that date from the Neolithic period in southeast Spain. THESE PIECES DEMONSTRATE HIGH STANDARDS OF QUALITY COMPARED WITH MORE MODERN PIECES. [ED. My emphasis]...  These pieces represented clothes, hats, tunics, sandals, baskets, and ropes—ALL MADE WITH THE FINEST TECHNIQUES. [ED. My emphasis]  In some cases, the artifacts included colored espartos." (Fajardo et al. "Traditional Craft Techniques of Esparto Grass...")
The authors list all the things that can be made with esparto:
Baskets (wide variety), Beehive, Belt for mules and donkeys, Bottle and container covers, Bowls, Canteen, Chair, Cheese mold, Clothing, Covered basket, Donkey pannier, Dough basket, Espadrilles Esparteñas, Fan, Ferret basket, Fishing net, Fish trap, Fodder basket to feed animals, specially mules and horses, Hat Sombrero, Long rug, Net for fishing or to carry straw in the cart, Oil mill basket for pressing olive pulp, Pitcher, Rope, Round rug, Saddle, Saffron basket to collect saffron flowers, Sandals, Shepherd spoon, Provisional spoon to eat curd, Shutters to keep the home fresh, Shepherd’s slings, Snail basket to catch snails, Sowing basket, Stool, Swarm catcher to catch bee swarms, Table mat, Toys and ornaments, Tunics.

Oldest wooden structure found in Zambia

The Oldest Man-Made
Wooden Structure
Found in Zambia
The Ideas of Rick Doble
who predicted the use of right-angle structures
in the Lower Paleolithic
by Rick Doble

NEW DIRECT EVIDENCE MAY CHANGE THE STORY OF PALEOLITHIC TECHNOLOGY AND HUMAN EVOLUTION 
This discovery supports the ideas, theories, and predictions of author, Rick Doble, in this eleven-year-old blog DeconstructingTime.

This discovery is:
-- a half-million-year-old wooden structure of carefully made interlocking logs built by early humans before our species, Homo sapiens. Archaeologists think it may have been a platform that was used to keep material dry above the wet ground. It was reported on September 20, 2023 in the journal Nature.

"Structural unit formed by two overlapping logs 
The underlying log passes through a central notch cut into the upper log ...and extends into the section. Plan view of the unit (left) and during excavation (right). The numbers refer to the distance in centimetres."

THE IMPORTANCE OF THIS DISCOVERY
It would be hard to overestimate the importance of this find. 
It is actual wood from the oldest wooden man-made structure that has ever been found.
#1. It is direct evidence of woodwork which has been almost impossible to find due to the fact that wood decays and leaves no trace.
#2. This artifact can be studied for the tools that were used to make it and the way the wood was cut from a specific kind of tree, and then scraped, shaped, and notched.
#3. Much can be inferred about the cognitive abilities of these pre-Homo sapiens because they imagined a design and then engineered a structure.
#4. Using state-of-the-art technology, it was carefully dated by a highly respected team of archaeologists to be at least 476,000 years old meaning that it was made by hominins who preceded our species, Homo sapiens. This means that hominins who came before Homo sapiens were much more intelligent than previously thought and had developed cognitive skills along with woodworking skills.

A SUMMARY OF HOW THIS DISCOVERY
SUPPORTS DOBLE'S IDEAS
ABOUT THE PALEOLITHIC ERA

Starting in 2014 I have written articles stating that:
-- Early hominins such as Homo erectus were much smarter than previously thought.
-- A well-developed plant material and fiber technology was probable with these early hominins.
-- They had some early stages of cognitive development.
-- An early sense of linear time was also developing as that allowed them to work with processes that required linear thinking. Processes require a step-by-step way of working from imagination to the final product. A process is itself linear.
--  The importance of right-angle construction by early hominins has been made evident by this discovery of two logs notched together at a right angle. I have written several articles asserting the critical importance of the right angle in early designs and structures.


DOBLE'S IDEAS AND THIS NEW DISCOVERY

This discovery supports and is consistent with my ideas throughout this blog but especially in my article "Terra Amata:...
the Oldest Paleolithic Building Site." that was published in this blog in 2021. 
See my article:
Terra Amata: the Oldest Paleolithic Building Site (December 2021)

The Terra Amata building site was indicated by post holes and is considered to be about 300kya. In my article, I make observations about Terra Amata that would also apply to this new half-million-year-old direct evidence discovery. I said that building a structure would have required advanced cognitive skills to design and plan along with cooperation and coordination among tribal members. The Terra Amata building site showed that pre-Homo sapiens, probably Homo erectus, were much more intelligent than previously thought and probably had also developed an advanced plant material or woven-fiber technology.

Both structures show an understanding of opposing forces. In the case of Terra Amata leaning poles were set against opposite opposing poles to make a hut. In Zambia, the structure showed a log that was carefully made with a notch that was placed at a right angle to another log. 

In my Terra Amata article and others in this blog, I have stressed the importance of the right angle and how it may have been a major discovery among early prehistoric people, an abstract structural principle that early hominins understood. This principle could have been used in basket making and other woven-fiber constructions as well as large structures.

This is a reconstruction of one of the 300,000-year-old Terra Amata huts in the Prehistoric Village of the Gorges du Verdon Museum in Quinson, France. The museum states, "The habitats [in their prehistoric village] have all been reconstructed based on research and observations by archaeologists. They are maintained by the museum's scientific team."

In both cases, the sophisticated use of wood where trees were cut down, trimmed, and shaped suggests that other plant materials such as fibers were probably used as well. I have proposed a theory that a woven-fiber technology or a technology based on basket weaving probably began among early hominins.

ABOUT RIGHT-ANGLE STRUCTURES
I consider the understanding of right-angle construction to be a major breakthrough for designing and creating a host of items. Since the logs were notched and deliberately placed at a right angle this discovery appears to support my idea.

HOW THIS AFFECTS MY NEW THEORY OF BASKET WEAVING OR WOVEN-FIBER TECHNOLOGY IN THE PALEOLITHIC

I have hypothesized that there was a plant-based technology developed by early hominins starting as early as several million years ago. Specifically, I proposed that a rudimentary basket weaving and woven fiber technology would have been possible among early hominins. 

This new discovery makes this idea much more probable. If hominins were making sophisticated wood structures a half million years ago, it is likely that plant technology had its beginnings hundreds of thousands of years before that. 

Virtually all anthropologists believe that early hominins used plant and fiber materials but disagree about the specific way they were used. I have proposed a basket weaving technology based on weaving fibers that could have started among the earliest hominins. And, of course, other uses were possible as well.

MORE ABOUT THIS NEW DISCOVERY

Buried in wet ground, archaeologists found the oldest known wooden structure that is about half a million years old (at least 476,000 years old). It was found near a river on the border of Zambia and Tanzania. Wood normally decays quickly and leaves no trace, but in this case, the logs were waterlogged which preserved them. Two logs were cut, scraped, and shaped and then joined at a right angle with a notched fitting. Because this structure is so old, older than the first evidence of our species, Homo sapiens, it must have been made by an earlier hominin such as Homo erectus. The researchers speculated that it was part of a platform that was used to keep materials dry above the wet environment. The highly respected team of archaeologists used state-of-the-art technology to date this 'platform'. This discovery is direct evidence of intelligence and cognitive skills by early humans. Until now it was assumed that early hominins were not very smart.

“It’s completely changed my view of what people were capable of that time,” said Duller, coauthor of the study, in the article in the journal Nature

"They used their intelligence, imagination, and skills to create something they'd never seen before, something that had never previously existed," Larry Barham, the lead researcher and a professor at the University of Liverpool who was quoted in this BBC report.

UNDERSTANDING EARLY HOMININ COGNITIVE THINKING

While it seems simple to us, the steps involved are mind-boggling when considering the invention of this construction by early hominins with smaller brains.

The 'platform' (if it was a platform) was designed to serve a purpose. No one knows the exact purpose but archaeologists guess that it could have been used to keep material dry above the damp ground. While we do not know the exact purpose, it does not matter when thinking about their cognitive skills. Whatever the specific purpose, there was a purpose and this purpose only makes sense if they had a sense of time. They needed to remember the past and how the environment operated over time with a periodically wet floodplain -- so the platform would function within that environment. Next, they needed to imagine a design which would satisfy that purpose. Such imaginative thinking required a sense of future time. Then they needed to plan and make tools for this work. After that, they cut down trees to obtain wood that had the right properties. Finally, they shaped the logs and notched them (like Lincoln Logs as one researcher said) so they would fit at a right angle. Right angle structures are quite strong but they do not exist in nature, so their cognitive skills had grasped a basic structural principle.
“I never would have thought that pre-homo sapiens would have had the capacity to plan something like this,” remarked Professor Barham who was a co-author of the study and who was quoted in this Smithsonian Magazine article.

HOW DOES THIS SUPPORT DOBLE'S IDEAS
ABOUT THE EVOLUTION OF TIME COMPREHENSION?

As you know this blog is about the 'Human Understanding Of Time' (HUT). It is my contention that the concept of time as we think of it today developed over millions of years from the immediacy of animal existence to our current concept of linear time today which has a past, present, and future plus duration. In this case, half a million years ago, these early humans appear to have had a sense of linear time when planning a task, otherwise, they could not have designed and built this 'platform'. They understood a need based on past experience, then imagined a design to meet that purpose, gathered the material, and then shaped and constructed it. This was a linear process that required a basic understanding of linear time.

However, having a basic sense of linear time does not mean that they understood time as we think of it today. It means, I think, they understood that a task or a process would require linear thinking.

One of my main themes has been, that early humans, i.e., hominins, were much smarter than previously thought. I believe they used the technology they had to the nth degree and that they were creative and inventive.

"I would say we need to consider these humans as having the ability to abstract forms from the environment and make them happen, and to pass [that knowledge] on through generations," said Professor Larry Barham. "And that's opened my mind to these pre-sapiens hominins being capable of what we would think of as quite complex behavior."

AFTERWORD 


EARLY HOMININS DEVELOPED ADVANCED TECHNOLOGIES CONTRARY TO  MODERN-CENTRIC THINKING

This next article of mine makes the argument that Paleolithic people developed a sophisticated woven-fiber technology, an idea that, until now, has not been accepted by anthropologists.

The Development of Advanced Woven-Fiber Technology in the Paleolithic Era: Insights from Paleo-Indian Artifacts and Ethnoarchaeology By Rick Doble  (January 2022)


FROM THE ABOVE ARTICLE
It is my contention that by the Upper Paleolithic, many technologies were quite advanced. In particular, basket weaving or woven-fiber technology had reached a high point of development. There is clay impression evidence of a variety of basket weaving techniques that had been mastered along with other evidence about the manufacture of cordage and the beginnings of textiles. This knowledge and these skills were then passed on to Neolithic cultures who were able to make full use of these technologies in their sedentary and agricultural societies. 

STONE AGE PEOPLE WERE INTELLIGENT AND KNOWLEDGEABLE
Almost ten years ago in 2014, I wrote two detailed blogs about the modern attitude toward ancient people, especially Stone Age people. Here is an excerpt. I listed many more biases so click on the links and read both articles.

The Moderncentric Bias Against Prehistoric Cultures: Part 1
(March 2014)

The Moderncentric Bias Against Old Stone Age Societies: Part 2 (April 2014)

BIAS #1:
OLD STONE AGE PEOPLE WERE BARBARIC SAVAGES
I believe the loaded words 'savage,'  'barbaric,' and 'caveman' are a kind of name-calling with little substance. Stone Age people had a sophisticated knowledge of their world. They studied and understood in-depth a number of things that we modern people are ignorant about.

“Savages we call them because their manners differ from ours.”
Benjamin Franklin
An example of skilled hunter-gatherer and early Neolithic basketry (detail on the right) found in the Cueva de los Murciélagos in southeast Spain (Andalucía, Albuñol). Recently these many baskets and woven items were found to be 2000 years older than previously believed indicating that some were made by European hunter-gatherers. These artifacts showed that hunter-gatherers were capable of well-made basketry accomplished with highly sophisticated woven-fiber technology.
