Researchers find evidence of interbreeding in human saliva

An experiment led by University at Buffalo scientists has revealed further proof of interbreeding among early humans. While studying the gene MUC7, which was previously proven to have evolved to serve an important purpose in humans, the researchers discovered a variant of the gene in the Sub-Saharan African population. The variant is further removed from the modern human population than Neanderthal MUC7, indicating an introduction of genetic material from a non-human species whose fossils have yet to be found.

The scientists exchanged data with other research institutions using NYSERNet’s R&E network.
