Oldest Homo Sapiens Found

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 鈥済arden of Eden鈥 but this find, thousands of miles away, shakes up what we thought we knew about human evolution and migration.
