Genetic Mutations evident in ancient human skull
A new research led by Erik Trinkhaus, an anthropologist at Washington University suggests that research done on a 100,000 old skull found in China, shows rare or unknown genetic abnormalities. It may suggest that the abnormality was the result of inbreeding, but it is not known if this is the case and if so to what extent.
The skull has a hole at its top that appears to have been caused by a rare genetic mutation. The researchers suggest that inbreeding may have been popular at that period of time due to the small and isolated populations of humans.
