patterns of evolution, types of natural selection & speciation

what is the change of 2 or more species in close association with each other (like plants and pollinators?)

coevolution

when the environment selects similar traits, like the stream-lined bodies and fins of sharks and porpoises, what type of evolution is it?

convergent evolution

name two types of divergent evolution

adaptive radiation + artificial selection

what type of natural selection does one version of the trait have the highest fitness over the average and the other extreme?

directional selection

what type of natural selection does individuals at either extreme have the highest fitness?

disruptive selection

what type of natural selection does individuals with the average form of the trait have the highest fitness?

stabilizing selection

what is the rise of two or more species from one existing species?

speciation

what type of speciation is due to differences in courtship or mating?

behavioral isolation

what type of speciation is due to timing of reproductive periods?

temporal isolation

what type of speciation is due to physical barriers

geographical isolation

what rate of speciation happens over a slow, steady rate over a long time?

gradualism

what rate of speciation happens in bursts?

punctuated equilibrium

what type of speciation is this?

gradualism

what type of speciation is this?

punctuated equilibrium
