Document Summary
Species don"t evolve in a vacuum - other species are evolving around them, often in way start affect other species. Coevolution: two (or more) species reciprocally affect each others evolution. Huge implications for human disease and for human interactions with the environment. Human disease:zoonotic diseases (jump from other animal species to us) are often the nastiest because w have"t coevolved with them. Just as species can coevolve, they also sometimes undergo speciation together. This is most common in parasites and the host they are completely dependent on (reproductive isolation!) Review: fungi are more related to nails than they are to plants. Protists/protozoa are so diverse that animals, fungi, and plants are more related to some form of protests than they are to each other. Used as catch-all category for any eukaryote not a plant, animal, or fungus. Because protist is basically a catchall category for many extremely characteristics besides being eukaryotic. Notable protists: unrelated species, there are no unifying.
