A new, typical genetic analysis of saliva has helped a team of international scientists to discover the evidence regarding the presence of ‘ghost’ species’ of archaic humans who may have bred with the forebears of the human being, currently living in Sub-Saharan African regions.  Putting it simply, during analysis, a team of scientists from the University of Buffalo has tracked down a protein found in saliva which indicates that the early Africans may have engaged in ‘sexual intercourse’ with a ‘ghost species’ of ancient humans.

As claimed by a team of scientists from the University of Buffalo, while reviewing and analysing the origins of the MUC7 protein -mucin antimicrobial protein that features antibacterial and antifungal activity and usually found in saliva and contributes to the slimy consistency of the split, have come across a strange type of evidence that revealed the existence of ‘ghost species’ of antiquated human beings. As believed by the scientists, these old and bizarre kinds of ghost species have bred with the forerunners of people, presently living various provinces of Sub-Saharan Africa.

As indicated by a previous study, MUC7 is more likely to contribute to an evolutionary benefit in early human genus because of its capability to bind microbe, and this feature of the protein helps the body to free itself from the sickness-causing bacteria. But now the new study has claimed that the process of interbreeding between the descendants of modern human beings in Asia and Europe with other hominine species, including in regions like Neanderthals and Denisovans used to take place, and this is what has baffled scientists most.

The stunning breakthrough also has indicated that the interbreeding between the forebears of human species was a lot more common than it previously thought to be. The new finding is also among the most recent genetic analyses that indicate that primeval Africans also had rendezvous with other prehistoric hominines. According to Omer Gokcumen, the lead author of the study and an assistant professor at the University at Buffalo in the US, “Or discovery seems that sexual intercourse between different early hominine geniuses is not any kind of exemption, rather it is more common in the early time.”

As confirmed by the lead author, when the researchers at the early stage of the gene that codes for the mucin protein MUC7, they found that they are same with the moniker of ancient admixture in contemporary time Sub-Saharan African populaces. For conducting the study, the team analyzed the MUC7 gene in over 2,500 modern human genomes. The complete details of the new research are published in the journal ‘Molecular Biology and Evolution over this weekend.
