Answer:
The Cactus with long spines should evolve while the cactus with short spines should extinct.
Explanation:
Natural selection was a term used by Charles Darwin to talk about the natural evolution of the species and how they adapt to different environments. The individuals within a certain type of animal or plant had variations one from each other. Those variations that can adapt to the environment in which they are placed are the ones that evolve because they live longer than the others.
In this case, the cactus with long spines will survive because it protects itself from animals better than the cactus with short spines. This last will extinct because eventually, animals will eat all of them.
