This question is very hard to answer as there is no evidence to point to the first human being. We do have evidence that other species before human being and they have already disappeared. In particular, the Australopithecus was particularly important and resemble very much to certain traits that a human being has. Take all the evidence together, most of the scientists believe that certain mutation made the homo sapiens sapiens more adaptable to his or her environment. By adaptation, we tend to consider the rate of survival and reproduction. Presumably, human beings were having more children than other close species that, at the end, were more "fit" to a particular environment.
