![]() The cactuses, the prey, may have evolved high branches so that the tortoises, the predators, can't reach them. On another island, where short-necked tortoises live, the branches are lower down. On one of the islands, where long-necked tortoises live, the branches are higher off the ground. Galapagos tortoises eat the branches of the cactus plants that grow on the Galapagos islands. This is true in all predator-prey relationships.Īnother example of predator-prey evolution is that of the Galapagos tortoise. An important thing to realize is that as both organisms become faster to adapt to their environments, their relationship remains the same: because they are both getting faster, neither gets faster in relation to the other. The fastest zebras are able to escape the lions, so they survive and reproduce, and gradually, faster zebras make up more and more of the population. We want your feedback!
