How does a predator / prey relationship lead to an evolution of a new population?

To survive being hunted by the predators, prey need to evolve to outsmart them.
Once all the old evolutions have become the new type, there is a new population.

U. life is what you go through to become a better person. it makes you stronger, wiser, and more creative. it can be hard but its ok. because i believe everyone was put here for a reason. whether or not you know that reason you should always look towards the future and trust in god for a better tomorrow.be safe and blessed
