149 stone flakes, hammers and anvils, found off at the Lomekwi 3 site on the shores of Lake Turkana, appears to have been crafted more than 3.3 million years ago — 500,000 years before our genus Homo. The authors reported their findings in Nature this week. Sonia Harmand and her team accidentally stumbled upon the ancient artifacts after taking a wrong turn and found a different place with stone tools on the surface of a site called Lomekwi 3.
