A Gene that could be evidence of evolution to Homo sapiens. A single change in a single gene, MYH16 may have caused gross anatomical changes that spurred human evolution. This work published by the University of Pennsylvania in Nature, suggested a gene could be responsible for the majority of jaw musculature, which was lost from human ancestors 2.4m years ago. MYH16 was found using a complex degenerative PCR techniqhes. The following website provides further, in depth information about these techniques.
