Answer:Evidence for evolution comes from many different areas of biology:
Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).
Molecular biology. DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.
Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.
Direct observation. We can directly observe small-scale evolution in organisms with short lifecycles (e.g., pesticide-resistant insects)

eye color isn't only inherited from your parents eye color. they could have recessive blue eye genes and have dominant brown eye alleles, therefore there is a chance you get blue eyes though both of your parents have brown. there is a fairly low chance, but it is still possible. let's say your mom has blue eyes and your dad has brown eyes, there is more of a chance that you get brown eyes, whereas if your dad also had blue eyes, you would have a 50% chance to get blue eyes since blue eyes are recessive. hopefully this helped ♡
