Darwin observed that in any given environment, there is a finite amount of resources available to support a population. This led him to conclude that individuals within a population must compete with each other for survival, and only those individuals that are better adapted to their environment will survive and reproduce. This process of natural selection leads to the evolution of new traits and ultimately to the formation of new species.
