You can learn a lot about humanity from the first technological revolutions of more than 10,000 years ago.

The human capacity for invention is unparalleled. We have developed technologies that have allowed us to survive and thrive far beyond the ecological niches that constrained our ancestors. While our innovation has allowed us to break loose from the constraints of our home continent, Africa, and even our home planet, the actual way in which our species adopts new technologies remains a subject of huge debate among those scientists who study the past. Does one hominid ancestor start to shuffle upright, and the rest follow? Does the first human to loop a piece of string through a shell bead inspire the rest of the species to create the world’s first jewelry? Or do different animals take up the same new adaptation at different times, because it solves a problem that appears in many places?

We know that in some of our closest living relatives, the primates, new technical skills are passed on through direct learning. Macaques, in particular, are responsible for innovative behaviors that have been transmitted through their societies by individuals who have seen and observed them and then adopted them as their own. This is true of behaviors as varied as “hot tubbing” by the macaques of Japan’s northern Hokkaido island and the habit of dipping sweet potatoes in the sea to “salt” them developed by macaques on Koshima island further south.

Many of the technological innovations that have had the greatest impact on our species were first seen about 10,000 to 15,000 years ago in a region that archaeologists refer to as the “Fertile Crescent.” The region encompasses a swathe of land crossing the countries between the easternmost Mediterranean Sea and the Sinai, Arab, and Syrian deserts and up into the Zagros Mountains of what is now Iran. It is a region of famous firsts in terms of radical changes to our species lifestyle: settling down, cultivating plants, and taming the animals we eat are all first attested in this strip of relatively abundant land.

It was along the shores of the Sea of Galilee where we have the first evidence of the wild ancestors of today’s wheat being exploited more than 20,000 years ago, at the site of Ohalo II, reconstructed from the microscopic remains of shattered seeds still clinging to a grinding stone after millennia. From 15,000 years ago, in a corridor stretching up and down the eastern Mediterranean we call the Levant, there comes the first signs of a new way of life for humans; one that involves staying in the same groups and homes all year round, rather than following food around the landscape as we had done for the 300,000 years prior. Those seeds from Ohalo II have grown into entirely new shapes by the time they are uncovered in these new inventions, called villages, and by around 9,000 years ago this new human-friendly type of wheat was well on its way to becoming our first domesticate (domesticate that wasn’t a dog—those we have had for probably 30,000 years). Meanwhile, over the last 10,000 years or so, goats, sheep, pigs, and eventually cattle were all brought into these new human habitations, and bred into the shapes that suit us rather than them: better to eat or easier to manage.
