Population is the unit of evolution. A population is defined as a group of organisms of a particular species that inhabits a particular area. Natural selection acts on traits within that population that are beneficial in the particular area. Another population of the same species may be under different selective pressures (as it is found in a different location), and natural selection may therefore act on different traits within that second population. The two populations, thus, may evolve differently. Therefore, the unit of evolution is the population, not species.
