Final answer:
Predator-prey coevolution, or the arms race, is an interaction between species where predators and prey continuously adapt to each other. An example is the relationship between bats and moths, where bats emit clicks to locate prey and moths have evolved ears to avoid detection.
Step-by-step explanation:
Predator-prey coevolution, also known as the arms race, is an interaction between different species that influences each species' evolution. It occurs when predators and prey continuously adapt to each other in response to their interactions. An example of predator-prey coevolution is the relationship between night flying bats and moths. Bats emit high-pitched clicks to locate prey, but moths have evolved simple ears to detect these clicks and avoid being caught. This constant adaptation ensures that neither species gains a significant advantage over the other, promoting their mutual survival.
