Evolution Review

Evolution is...

• errors in an individual's genetic code (DNA) that leads to changes in the genotype and/or phenotype of that organism

• shifting of traits to better align with the environment

• the change in characteristics/traits of a species over a long period of time (many generations)

• anatomy that supports common ancestry (homologous, analogous, and vestigial)
