Book Review: The Acheulian Site of Gesher Benot Ya’Aqov, Israel: The Wood Assemblage

The Acheulian Site of Gesher Benot Ya’Aqov, Israel: The Wood Assemblage

by Naama Goren Inbar

My rating: 4 of 5 stars

A readable monograph, which sounds like an oxymoron but is actually a rarity. Lots of scientific detail. I read it to get better insight into this part of Israel during the middle Pleistocene, the time Homo erectus was emigrating from Africa to the world. Yes, I got some of that, though the author refused to draw conclusions from her collected data. This was my personal disappointment, but gave me respect for the type of scientist Dr. Inbar is. I’ve looked for the other books in the series (this one only covers the wood detritus collected at the site), but they either were never written or are unpublished.

The Uncontrollable AI

Lucy: Her Story of Survival

Otto is not listening–again. The first time this happened was with Lyta.

Now, he has found a beautiful female Homo erectus. She’s a warrior, strong powerful. She lives in Africa so wears no animal skin clothing to protect her from the cold.

Here are a few more pictures of Lucy, her clan, her habitat:

Homo habilis vs. Homo erectus

Homo erectus–note the width of the skull and the less-protruding snout

My passion is studying early man, specifically how we became who we are. Is our violence an aberration or part and parcel of survival? No other mammal kills their own, but maybe–as the alpha on the planet–our greatest threat to our survival is our own species, so we’re forced to destroy each other.

What was lacking in H. Habilis that led to their extinction, to be replaced by the big-brained, scrawny Homo erectus? Habilis was preyed upon by species with bigger claws, sharper teeth and thicker skin. Habilis (and my friend Lyta) scavenged their left-overs, in between hiding from the imposing mammals that dominated the Plio-Pleistocene African savanna. But, eventually hiding wasn’t enough and H. erectus took over (we don’t know if they fought with each other or if habilis left ‘with a whimper’).

H. erectus, with his longer lower limbs for running and walking efficiency, his bigger brain especially in the areas for planning and forethought (and speech depending upon whose research you’re reading) was tall, thin, and barrel-chested, hardly daunting in a world of sabertooth cats, mammoth and giant sloths. Yet , it is he who spread from Africa to China, India, the Middle East, Java. It is he–not predator cats or alligators–who developed a highly adaptable culture allowing him to survive a wide range of climates and habitats.

That is the first of their firsts. Want more?

• first appearance of systematic hunting.
• first use of fire (though arguably no control of it)
• first indication of extended childhood (thanks to the helplessness of their infants)
• first indication of the ability to lead a more complex life (their Acheulian tools were sophisticated, their hunting was planned)
• first to wear clothing (how else to survive Georgia and China)
• first to create complex tools and weapons

Lucy: A Biography–Part XXIII

Finally after ten years, I am close to publishing the heart-rending and fast-paced biography of Lucy. Written in the spirit of Jean Auel, this is the paleo-historic saga of our earliest ancestors as lived through the eyes of a female Homo habilis.

Since Donald Johanson uncovered the tiny three-and-a-half foot clawless, flat-toothed Australopithecine, we have asked, Who is she? And how could she survive in a world of mammoth predators and unrelenting natural disasters she had no understanding about? This book answers those questions as well as more fundamental ones like, Where did God come from? Why did man create his first tool? How did culture start?

Here’s a summary:

Lucy: A Biography follows three species of early man (Australopithecus, Homo habilis and Homo erectus), as they fight for the limited resources of Pleistocene Africa. Lucy, of the species habilis, blames herself for the death of her family and agrees to mate with a stranger (Raza). As they journey to Raza’s homebase, they are tracked by two deadly predators: Xha, of the smarter and more powerful species Homo erectus, and the violent and unforgiving Nature, a sentient being who meddles with fate and Lucy’s future as though it were a chemistry experiment. The story is carefully researched to shared the geography, climate, and biosphere that would have been Lucy’s world 1.8 million years ago, when man was not King and nature ruled with a violence and dispassion we call ‘disaster’ today.

Every week, I’ll post part of this story.

A note: While I took Lucy’s name from the infamous Australopithecine skeleton discovered by Donald Johanson, Lucy is a Homo habilis. Her adopted child Boa is an Australopithecine.

Book Review: Evolution of Homo Erectus

Across the planet

Evolution of Homo erectus by G. Philip Rightmire is a scholarly discussion of Homo Erectus’ evolution through time, across the planet, through his diverse global locations–China, Africa, Indonesia, Spain, Europe, including Trinil, Sangiran, Zhoukoudian, Ternifine, Sale, Turkana, Olduvai Gorge.  Rightmire has studied the major artifacts and provides a rigorous overview of each, including sketches, dimensions, various views, discussion and analysis. Dimensions include not only the major measurements, but breadth, height, diameter, of the parts of each artifact. On Page 6, he includes two tables that inventory the body parts of samples found in the principal Indonesian and Chinese localities, as well as Africa (northwest, east and south). I found those tables fascinating.

The Importance of Running to Man

Man seems an unlikely survivor of the primal world. We don’t have claws like Dinofelis, deadly teeth like Sabertooth, thick skin like early rhinos, or the huge size of a mammoth. How did we escape becoming the favorite snack to all these better-equipped predators?

One way is we learned to run. Not the sprint of a gazelle who can take off and flee at an outrageous pace. Like her, many Pliocene animals relied on quickness and speed to escape predators or catch prey. Few had resources beyond that initial sprint.

We weren’t as swift as our four-legged competitors, but when the gazelle quickly tired and had to stop to regenerate, we kept running. In fact, even then, we could run great distances which enabled us to chase down prey when they tired and overheated.

Did Environmental Change Cause Human Evolution?

After reading this scholarly research on human evolution, I came to believe the authors’ hypothesis: Environmental change caused human change. See if you agree:

Evolution on a Restless Planet: Were Environmental Variability and Environmental Change Major Drivers of Human Evolution?
Peter J. Richerson, Robert L. Bettinger, and Robert Boyd
7.1

How Homo Erectus Made His Tools

Ever wonder how those scrawny protohumans without claws, sharp teeth or thick skin survived the likes of Sabertooth? Me too, so I researched it and ended up with a dashing tale, full of suspense, drama, and the appealing characters that we moderns can relate to. What didn’t kill them made them stronger, and isn’t that what Darwin predicted when he labeled evolution ‘survival of the fittest’?

Early man, especially by 1.6 million years ago when Homo erectus first arrived on the planet, learned that they couldn’t survive without weapons to balance the odds. Prior to H. erectus, it was a simple primitive rock, sharpened at one end for cutting and chopping. By the time of  Erect Man, he used stone tools to break, crush, split and cut up difficult vegetable and animal foods. His tools replaced his flimsy fingernails, his small dull teeth, and allowed him to cut through thick animal skins. They took the place of the Sabertooth’s powerful jaws and enabled Man to crush long bones and extract the nutritious marrow.

We know something more about Homo erectus from the stone tools–the handaxes, picks, scrapers, awls and cleavers–he left behind: He was highly intelligent. Not only did it require good eye-hand coordination and a precision grip to strike core with hammer stone and create these tools, but their three-dimensional symmetry reflects a Euclidean sense of space and an ability to follow a plan over a prolonged period of time to create the beautiful, well-knapped handaxes they created by the thousands.
