Human evolution or paleoanthropology is a theory within evolution which posits that mankind evolved from more primitive species over the course of 40 million years, with the most dramatic changes occuring during the last 2 million years. An absence of intermediary fossils, no plausible pathway for the development of the brain, and countless other disproofs to the theory has rendered human evolution more of a philosophy of a belief system rather than a valid scientific concept.
