Distinguish between microevolution and macroevolution. Examples of evidence could include similarities in DNA sequences, anatomical structures, and order of appearance of structures in embryological development. In sympatric species, does natural selection favor pre-zygotic barriers or post-zygotic barriers? I for one can't tell the African fish eagle and the bald eagle apart from the photos below. Broadly speaking, different species are unable to interbreed and produce healthy, fertile offspring due to barriers called. The biological species concept defines organisms as being, or not being, of the same species based on whether they can interbreed to make fertile offspring.
