Amensalism -/0 interactions - : one species is harmed while the other is unaffected Tend to be more accidental than other relationships Example: a herd of elephants that crushes plants and insects while moving through a forest . Commensalism +/0 interaction: - one species benefits while the other is unaffected Brown-headed cowbirds follow grazing cattle and bison, foraging on insects flushed from the vegetation. Cattle convert plants into dung, which dung beetles can use. Dung beetles dispe...

adaptions - inherited aspects of an individual that allow it to outcompete other members of a population that lack the trait (or that have a slightly different version of the trait). Adaptions are traits that have evolved through the mechanism of natural selection analogous traits - similar because they have converged on shared form. they are not derived from common ancestor apamorphy - • a form of a derived state Australopithecines - members of the hominin genus Australopithecus biolog...

*The scenario: In a single, isolated population, mutations of each of the three types in options a-c below occur, and the resulting genotypes ultimately become fixed in that population. Other populations never experienced these mutations, so the original genotypes remain. Now we'll hybridize members of that isolated population to members from one of the others. -Which of the following types of mutation is MOST LIKELY to cause reproductive isolation as a side effect? - Large Inversion ( chr...
