Question

At its most basic level, evolution is a:
A) change in the frequency of alleles in a population.
B) change in the frequency of alleles in an individual.
C) new species arising from an existing species.
D) change in an individual's phenotype caused by mutations.

Accepted Answer

Evolution refers to a change in the frequency of alleles (different forms of a gene) in a population over time, leading to genetic and phenotypic differences between populations and the emergence of new species. Evolution occurs through mechanisms such as natural selection, genetic drift, mutation, and migration.
