Explain the theory of evolution
please

As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve.

Explanation:

evolution is fueled by something called natural sellectoin to explain this lets say a species of birds move to an island where there are more seeds the ones that are able to eat will survive and reproduce and they will reproduce most times they will overproduce so there is a higher chance of surviving and there bodys will slowly change like the mucles will become stronger along with the beak that is baisicly evolution but this does take millions of years this not a few years and they change this is s extremly slow change.
