Overpopulation leads to competition for limited resources amongst the individual of population. There is variety amongst the individuals within a population. Some varieties are more advantageous within a given environment than others. Therefore, the individuals that possess the characteristics that are less advantageous to the environment will be more likely to perish.  Likewise, the individuals that possess the more advantageous variations will be better adapted to their environments. Such individuals will be more likely to obtain the limited resources and survive in that particular environment.  As a result, the survivors will have more opportunities to produce offspring. Over time, the genes of the survivors will become more prevalent within the gene pool of the population. As time passes, the results will accumulate and a new generation will be created in which the individuals obtain the favorable characteristics that make the species better adapted to its environment.

 In this way, overpopulation causes natural selection that leads to evolution.
