The Whole Story of How Humans Evolved From Great Apes
The picture of human evolution has changed repeatedly and dramatically over the past half century, shaped by waves of new fossil discovery, technology, and scientific techniques.
Together with the first archaeological finds of stone tools and cut marks on animal bones indicating butchery, these fossils combine to show us that Homo had become highly successful within a million years of its origins, and had spread out across Asia as far as China. This tool kit literally gave early Homo species a cutting edge in the struggle for survival in varied environments, and may have been a key factor underlying their ability to expand their niche into new areas, including Jordan, north India, and China well over 2 million years ago. To the east, DNA studies have recognized a probable sister group of the Neanderthals, the Denisovans —best known from Denisova Cave in the Altai mountains of Siberia—while to the south, Homo naledi was still there, and the Kabwe skull from Zambia is evidence for at least one other species.
