Discuss coevolution as it relates to predator-prey interactions. Include a brief discussion of two specific examples. What will be an ideal response?
Predation has resulted in a co-evolutionary “arms race”of predator strategies (more efficient
ways to catch prey) and prey strategies (better ways to escape the predator).
An example of a predator strategy is increased speed of the brown pelican chasing fish. Some
plants escape predators by physical characteristics such as spines and thorns which
discourage herbivore predators.
