Patrilineal and matrilineal most recent common ancestors (MRCAs) of living humans roughly between 200 and 100 kya [56] [57] with some estimates on the patrilineal MRCA somewhat higher, ranging up to 250 to 500 kya. [58] 160,000 years ago, Homo sapiens idaltu in the Awash River Valley (near present-day Herto village, Ethiopia) practiced ...
