SELECT ALL THAT APPLY: In the context of a natural habitat, which of the following must be true for two birds to be considered the same species?

• They must be able to mate

• They must be able to produce viable offspring

• They must have structural similarities

• They must have the same bone structure

Genetic diversity is decreased through this process.

• Gene Flow

• Genetic Drift
