Solution

The statement you provided is defining the concept of "Evolution". Evolution is defined as a change in allele frequencies in a population over time. Here are the steps to understand this:

  1. Alleles: These are different forms of a gene. For example, a gene for eye color may have different alleles that result in blue, brown, or green eyes.

  2. Population: In genetics, a population is a group of individuals of the same species that live in the same area and interbreed.

  3. Change in allele frequencies: This means that the proportion of different alleles in the population changes. For example, if a population of 100 individuals has 50% blue eye alleles and 50% brown eye alleles, and over time the proportion changes to 60% blue and 40% brown, this is a change in allele frequencies.

  4. Over time: Evolution is a process that happens over generations, not within a single individual's lifetime. Changes in allele frequencies are measured from one generation to the next.

So, putting it all together, evolution is the process by which the proportions of different alleles in a population change from one generation to the next.
