Oldest Homo Sapiens Found

A discovery of the oldest Homo sapiens remains shakes up our ideas of human evolution. Also, what the US withdrawal from the Paris agreement means, and β€˜why do people cooperate?’

The oldest fossils of Homo sapiens have been unearthed in Morocco. They are over 100,000 years older than the next oldest H.sapiens fossils, and show subtle differences in brain size and appearance from modern man. We were thought to have originated in an East African β€œgarden of Eden” but this find, thousands of miles away, shakes up what we thought we knew about human evolution and migration.
