Evolution: The change in allele frequency in a population over time.
Causes:
Drift: random changes that occur in small populations
Immigration/emigration: new members of the population have a different genetic makeup than the original members
Natural selection: organisms with particular alleles survive better than those with alternative alleles or have more offspring.

Additionally, the characteristic must influence the survival and reproductive success of individuals in a population. These two factors are essential for natural selection to operate and lead to evolutionary change.
