Ancient Africans possibly interbred with “ghost’’- Study

Human ancestors living in Sub-Sahara Africa may have interbred with unknown “ghost’’ species of early hominins, a study on the evolutionary history of a salivary protein has indicated.

“This unknown human relative could be a species that has been discovered such as a subspecies of Homo erectus, or an undiscovered hominin,’’ Omer Gokcumen, assistant professor at the State University of New York at Buffalo, said in a recent statement.

“We call it a “ghost” species because we don’t have the fossils,” he added.

The new research is among the most recent genetic analyses indicating that ancient Africans also had trysts with other early hominins.

The research team traced the evolution of an important mucin protein called MUC7 that was found in human saliva, examining its gene in more than 2,500 modern human genomes.

“When we looked at the history of the gene that codes for the protein, we see the signature of archaic admixture in modern day sub-Saharan African populations,” Mr. Gokcumen said.

The research team found that a group of genomes from sub-Saharan African populations had a version of the gene that was wildly different from versions found in other modern humans, even beyond the differences between modern humans and the Neanderthals or Denisovans.

The finding, published on Britain’s Molecular Biology and Evolution journal, showed that the ancestry of Homo sapiens are more complicated than originally believed.

Study showed that genes mutate during the course of evolution.

Thereby researchers calculated that the ancestors carrying Sub-Saharan MUC7 variant interbred with the “ghost’’ hominin species as recent as 150,000 years ago, after the two species’ evolutionary path diverged from each other some 1.5 to 2 million years ago.

The new studies also found that the MUC7 gene helps give spit its slimy consistency and binds to microbes, potentially helping to rid the body of disease-causing bacteria. (Xinhua/NAN)

    Humans did not evolve from lower species. Humans were deliberately created through genetic manipulation of hominid species found on earth.

    We will begin to know the truth when we start to accept the fact that our so called knowledge is grossly incomplete. After searching for the “ghosts” and the “missing links” we will come to appreciate the reality of creationism. Everything about the history of life keeps changing by the day and as we make more discoveries we realise that the premises we had built about human existence and origins are on rickety foundations. Whoever likes can stick to the old fable that life started by accident and mankind evolved from apes. One thing I know is that I am no descendant of an ape; I was wonderfully and beautifully made.

      no the evolutionist are not saying that you evolve from apes, what they are saying is that they, the scientists did evolve from apes and i concur with them because they think like apes.

        Hahahaha…
        Nice one, Charles..

    Now I can unduerstand why we (africans) have so many spiritual churches, can see visions, walk on top of the sea and have colonised other planets.

    And white people are the off-springs or mutants of that cross-breeding.

    Another confusion theory, scientific researchers I hail thee…but my worry is that we blacks are always at the bashing end.
