Document Summary
Outcomes: race factors that advantage one side or the other in an evolutionary arms race: mutualistic, competitive and antagonistic relationships between species, given "real world" examples. 2: meaning of "life-dinner principle, difference between prudent-parasite hypothesis and trade-off hypothesis, in terms of the evolution of virulence factors that influence the optimal virulence of a given host/parasite relationship. 5: costs and benefits of being highly virulent (from the point of view of the parasite, why improving equipment for survival does not always translate into "winning" an evolutionary arms. Ex. flowering plants and their pollinators (bats, birds, insects) Plant gets its gametes moved around and bat gets nectar reward. Ex. food that lion eats is not available to cheetahs reduction of pop size. Results in loss of pop of some species due to loss of resources when competing with other species. Antagonism one benefits, the other incurs costs. Ex. predator prey relationship ex. turtle eats fish, fish dies but turtle gets food.
