Human Evolution To understand the story of human evolution, we must understand both our ancestry and our relationship to our closest living kin. http://myweb.students.wwu.edu/~christ39/Images/Human%20Evolution.jpg

Who studies Human Evolution? Scientists who study fossil evidence of human evolution are called paleoanthropologists or biological anthropologists. Much of the information available about human evolution comes from the fossilized bones of early hominids, a group that comprises humans and their immediate ancestors.

Why Study Human Evolution? Remember evolution is the change in allele frequency over time. To look forward into the future of the human race we must study where we have been. http://www.arts.uwaterloo.ca/~acheyne/index_files/guards.jpg
