Ancient DNA reveals ‘into Africa’ migration

An ancient African genome has been sequenced for the first time.

Researchers extracted DNA from a 4,500-year-old skull that was discovered in the highlands of Ethiopia. A comparison with genetic material from today’s Africans reveals how our ancient ancestors mixed and moved around the continents. The findings, published in the journal Science, suggests that about 3,000 years ago there was a huge wave of migration from Eurasia into Africa.

This has left a genetic legacy, and the scientists believe up to 25% of the DNA of modern Africans can be traced back to this event. “Every single population for which we have data in Africa has a sizeable component of Eurasian ancestry,” said Dr Andrea Manica, from the University of Cambridge, who carried out the research. Edited from: Ancient DNA reveals ‘into Africa’ migration

    Well; there’s a surprise! Here was H sapiens hanging about in Africa until 60 Ka, while the Denisovans, Neanderthalers, and Heidelbergers were roaming everywhere all over Europe and Asia. Once H sapiens finally got into Europe, some of them couldn’t wait to get back to Africa. Was it the awful weather, the cooking, the lack of elephants, or (my pet theory) they didn’t want to be conscripted to build any more giant stone Neolithic monuments.
