They found that East African populations now have as much as a quarter Eurasian ancestry. Meanwhile, twist those in the far west and south of the continent still have at least five per cent of their genome from Eurasian migrants. This map shows the proportion of West Eurasian component, λmota, lbk, across the African continent. This graph shows the mixture of genes that came over from Eurasia in Africa. Contemporary populations are in blue, and ancient genomes in red. The bars represent standard error between what is normal. The skeleton found in Mota cave is related to the Ari, who are modern-day ethiopian highlanders 'This paper is exciting because it is the first to get ancient dna from Africa said david reich, a geneticist at the harvard Medical School. 'i think the analyses are also interesting, in particular, the claim that all sub-Saharan Africans today have a substantial amount of ancestry from back-to-Africa migrations.
It's not clear why they moved, though one theory that's been suggested is that farmers looking for fertile land traveled up the nile. This Stone Age resettlement had previously been theorised, but the rare find allowed scientists to see what dna looked like well before the time the migration would have taken place. A comparison with modern populations around the world allowed them to see that the migrants left their genetic mark in the furthest corners of Africa. 'This is the first ancient human genome found in Africa to have been sequenced said Marcos Gallego Llorente, a geneticist at the University of Cambridge. Previously, scientists had only been able to sequence dna from samples found in northern and Arctic regions, because the climate there allows genetic material to survive for longer. In 2011, archaeologists with the help of local people discovered a cave containing the bones of a man - dubbed Mota, who died around 2,500 bc and from whose temporal bone they managed to extract intact dna. By comparing this ancient dna with modern samples, researchers were able to map genetic changes that have taken place in the past 4,500 years.

A skeleton of a man buried 4,500 years ago in an Ethiopian cave has allowed scientists to sequence one of the first ancient African human genomes. Dna extracted business from the skull supports the theory that a wave of Eurasian farmers migrated back into Africa some 3,000 years ago, researchers say. These farmers' dna reached far into the continent, spreading groups previously considered to be isolated, such as the Khoisan of south Africa and the pygmies of the congo.
Dna extracted from the skull supports the theory that a wave of Eurasian farmers migrated into back into Africa some 3,000 years ago, researchers say. This image shows an excavation of the rock cairn under which the burial was found. Mankind's great u-turn, when humans first left Africa some 60,000 years ago, they went on to leave their genetic footprints around the world. These same footprints have revealed that some humans decided to return to Africa, carrying genes from the rest of the world back to the continent. Researchers have so far now identified two migrations from Eurasia into Africa: One about 3,000 years ago, of non-Africans entering east Africa, and a second one 9001,800 years ago. The number summary of migrants flooding into the horn of Africa 3,000 years ago may have amounted to over a quarter of the population of the region at the time.

Payton, knopf of the United States Institute of peace explains that the fighting has devolved from a war between government Dinka and nuer factions to include more local or regional issues.
