Humans evolved in southern Africa around 200,000- 350,00,000 years ago, then expanded out to the rest of the world around 100,000 years ago. Several lines of evidence point to an African origin for Homo sapiens. Human diversity is highest there, both in terms of genes and languages, suggesting a long…

The first modern humans appeared between 200,000 and 350,000 years ago, based on estimates made from our DNA. However, no bones of modern Homo sapiens are known from this time, or for tens of thousands of years afterwards. Instead, we have fossils of primitive-looking Homo sapiens- people with big brow…
