Earlier studies found evidence that the ancestors of modern humans in Europe and Asia interbred with other hominin species, which include the Denisovans and the Neanderthals. Now, analysis of saliva suggests that ancient Africans had similar trysts with other hominins.

The research, which was published in the journal Molecular Biology and Evolution on July 21, suggests that a "ghost" species of ancient humans may have contributed genetic material to the forebearers of modern-day humans who now live in Sub-Saharan Africa.

MUC7 Protein In Saliva
Study researcher Omer Gokcumen, from the University at Buffalo College of Arts and Sciences, and colleagues traced the evolution of a protein found in saliva known as MUC7.

The protein gives spit a slimy consistency. MUC7 is also believed to enhance saliva's ability to bind to microbes, which is crucial to preventing disease, as this clears away unwanted pathogens from the mouth.
