A US study found that some West African people could inherit unknown ancestral genes.
According to the daily mail, researchers at the University of California, Losangeles, analyzed 50 West African people from the West Africa, DNA, and found that about 8% of the DNA came from an unknown "ghost" ancestor.
Though Homo sapiens may be the only ancient race to remain today, tens of thousands of years ago, there were several ancient humans on the planet. They cross and reproduce, making some of the extinct DNA of ancient humans left in modern people, such as the discovery of Neanderthal DNA in people outside African descendants, and the discovery of the Danny SW DNA on the Asian descendants.
The researchers said, DNA analysis showed that the Yoruba "ghost" ancestors may not be Neanderthals or Danny Suowa people. They speculated that the "ghost" ancestor may be a Heidelberg native who lived in Africa about 200 thousand years ago, or so far unknown.
Mark Thomas, a professor at the University College London, told the magazine New Scientist that no matter what the "phantom" ancestor's answer is, the study again did not evolve from a single population.
