As far as I know, evolution usally occurs with groups of species. No 1 animal can evolve, the changes happen from generation to generation. So there will always be more then just 2 animals involved. Thats where variation comes in, each animal has slightly diffrent traits then one another and those with the best suited to their enviorment have a higher chance of survival. Those traits are then passed down to their next generations. This usally takes many generations over thousands of years to notice great change....at least thats how the theory goes
