With stone tools, hominids could add much more meat to their diet, even if they didn’t have the paws of a hyena or the claws of a lion. The devolution of big brains raced on, and in the few hundred thousand years, hominids, known as “Homo ergaster,” were the first to warrant the title of human beings. Like modern humans, they had a wanderlust, and before long they left Africa altogether. By 1.7 million years ago H.ergaster had reached what is now the Republic of Georgia near the Caspian Sea, where they left behind skulls and tools.

The invention of hand axes and other new stone stools allowed the African hominids to full their hungry minds. Brain tissue demanded 22 times more energy than the equivalent piece of muscle at rest, and hominids now had gigantic brains to feed. Hominids may have used their new tools to get more meat, butchering bigger animals with tougher hides. But if having hunter-gatherers are any indication, these hominids did not survive on meat alone. ~ Page 267
