Expert Answer:

Migration, natural selection, gene flow, new species. 
Example - if the population of red beetles suddenly becomes too much and all move to different bushes, then its migration will lead to natural selection. If a beetle from one bush migrated accidentally to the other bush, then if it is capable of mating with the beetles present in the bush then gene flow shall occur... if not, then the group, is said to be a new species and if the beetle mates then still there are chances of new species to be formed.
