The Ghost Population
According to the research published in the science advance journal, it said that the ‘archaic ghost population’ looks like it might have diverged from the modern human being. That was before the splitting of Neanderthals from the family tree.
The splitting suspected to have taken place between the year thirty-six thousand and million years ago. This is according to the University of California, Los Angeles. Ancient humans had born babies with present-day African ancestors. This is just as the Neanderthals gave birth with current day Europeans’ ancestors. Arun Durvasula and Sriram Sankararaman geneticists wrote.
The Researchers Report
The modern West African’ genetic ancestry comprises two percent to nine percent of this Archiac population DNA. They continued.
Established research has also shown that modern European populations had the DNA of Neanderthals. In the oceanic community, they’re found that there is an existence of Denisovan DNA. The UCLA researches said, “while several studies have revealed contributions from deep lineages to the ancestry of present-day Africans. The nature of these contributions remains poorly understood.”
Because of difficulty in getting the ancient DNA and rare fossils record in Africa, the information is not complete.
To find the ‘ghost’ of the hominin tribe, using computer modeling strategies on the modern DNA, the UCLA scientists had to overcome those challenges. The scientists continued to say that they built “genome-wide maps of archaic ancestry” across the four west African ethnic that lives un those three countries; that is Sierra Leone, Ghana, and Nigeria.
Comparison of the Hominin DNA
The researchers made a comparison of four hundred and five genomes of west Africans with those of Denisovan genomes and Neanderthal. They were working out if there was interbreeding amongst the hominin whose ancestors separated from the family tree. The data shows that there was the involvement of multiple populations.
A bio-archaeologist, Professor Joel D. Irish from Liverpool John Moraes University, in an interview with CNN, he told them that there could be many ancient human populations that differ from each other.” I think at one time. There’d have been many communities, with genetics different enough to look abt different. Everybody mates with everybody. I think we will find more and more of these “ghost” populations coming up. He said.
Africa the Origin of Human
The scientists in the year 2010 discovered that the earlier ancestors of Asians, Europeans, and Americans had done reproduction with Neanderthals. This was after extraction of the first genomes from bones of the stone age hominins.
Researchers from Princeton’s Lewis–Sigler Institute for Integrative Genomics, last month said that they detected ancestry of Neanderthal in Africans for the very first time. The data showed that modern humans in about 200000 years ago, left Africa for Europe. They then interbred. They later went back to Africa.
