Match the following

• speciation

• when two populations can no longer interbreed and become 2 different species

• species

• 2 populations that are dependent on each other so they evolve together

• sexual selection

• mating behaviors/traits are still shown, even if they could cause harm

• coevolution

• 2 populations who can interbreed

• 1 of the conditions of no evolution

• large population

Fox babies that are too small won't survive and those that are too big need too much food to survive but the ones that are born with medium weight are developed enough without needing too much food, what type of selection is this?

• directional

• stabilizing

• disruptive

• geographic

Match the following

• embryology

• change in a population over time

• homologous structures

• Similar structures evolve independently, form because of similar environments

• macroevolution

• change in a species overtime

• analogous sturctures

• Similar structures evolve from same common ancestor

• microevolution

• study of early development shows proof of common ancestor
