Document Summary
In reality, it is more complex than just one missing link. Using fossil and artifacts, paleoanthropologists study early human evolution. 2,000,000: stone toolmaking, hunting and gathering, bipedalism begins. Charles darwin searched for the missing link between apes and humans. Evolutionary change is often described as differential reproductive success, and natural selection is the principal, though not the exclusive, mechanism responsible for it.
