 The Human Evolution gallery at Natural History explores the origins of Homo sapiens by tracing our lineage back to when it separated from that of our closest living relatives, the bonobos and chimpanzees. Around 200,000 years ago, Africa was where modern humans developed. They have smaller faces and brow ridges, a chin that is more prominent than that of other ancient humans, and a brain case that is higher and more rounded. Modern human fossils from Israel (around 100,000 years old), Africa (around 195,000 years old), and Australia (around 12,000 years old) are among the casts on display. These fossils demonstrate that typical characteristics of modern humans evolved over time rather than emerging fully formed from Africa. They also suggest that at least two waves of people leaving Africa may have occurred, one about 100,000 years ago and the other about 60,000 years ago. We are all descendants of those who left during that second migration wave outside of Africa. Source: Natural...

 According to a new study, the first farmers from Central Europe used milk around 7,400 years ago in the early Neolithic era. This helped humans learn how to eat milk and laid the groundwork for the dairy industry. A ground-breaking method was used in the international study, which was led by the University of Bristol and was published today in the Proceedings of the National Academy of Sciences (PNAS). It was used to date dairy fat traces that were preserved in the walls of pottery vessels that were made in the 54th century BC. Because it targets fatty acids from animal fat residues, this method is especially useful for determining when new foodstuffs were introduced in prehistoric times. Dr. Emmanuelle Casanova, the lead author, said, "It is amazing to be able to accurately date the very beginning of milk exploitation by humans in prehistoric times." She conducted the research while completing her Ph.D. in archaeological chemistry at the University of Bristol. By introducin...
