How does variation among individuals relate to evolution (change in genetics over time)? explain how variation in a population leads to a change in the relative frequencies of alleles, and could lead to the formation of a new species. (a complete answer should be at least a paragraph in length).

! i will give

Variation among individuals relate to evolution because in natural selection, only the best survive to reproduce. Therefore, there needs to be variation so some organisms can be better then others. For example, lets say there is a species of finches that rely on seeds for food. Some finches have small beaks, and some have large ones, which is the variation. The seeds they feed on are big and tough to crack. This means that the finches with larger beaks would be better fit for these conditions. Meaning those finches would survive,
And finches with smaller beaks would not. This ties into allele frequency because they would have more big beak alleles. Also, this
Could lead to a new species over time because of the change in beaks.
