Microevolution

Explanation:

A population is a number of organisms of a species found in a particular area and can interbreed.

Microevolution, or evolution on a small scale, has to do with a change in the frequency of gene variants, alleles, in a population over generations.

If there has been a change in allele frequencies in the population over generations, we can say that the population has evolved, that is microevolution has occurred.
