I hope u meant apes from primates....but u look at the different splits dents and homes in the skulls to determine if they have a common ancestor. u can also compare skull size and density. hope this helps ♥
A very small portion of colorectal cancers are caused by inherited gene mutations. Many of these DNA changes and their effects on the growth of cells are now known. For example: Familial adenomatous polyposis (FAP), attenuated FAP (AFAP), and Gardner syndrome are caused by inherited changes in the APC gene.
