It has been proposed that many of the muscles attached to the human ear served a purpose in other primates to help direct the ear toward sounds or otherwise move it. Human ears do not move much, despite the muscles attached to them. Thus, there is a hypothesis that human ear musculature no longer serves its original purpose, nor does it have a new purpose. If that is true, which of the terms below best describes these muscles? * This was in your readings, but we haven't talked much about it in class. O adaptation O acclimitization O vestigial O natural selection O none of these is appropriate O sexual selection

Human Evolution

Human evolution is the process of evolution of humans from early man to anatomically modern humans. The process of evolution in humans leads to the gradual development of traits like bipedalism. Humans are the highly social animals that make them the most advanced animal on Earth.  Human evolution is an outcome of interaction among the following processes:
