QUESTION 1
Behaviors evolve in one species and not in other species because of the following reasons:
All animal species are composed of different genes in their bodies which controls their physical appearance and behaviors. Genes of a particular species cannot be shared to another animal species. That is the reason why animals like goats cannot breed with sheep because their genes are incompatible (Nowak, Tarnita & Wilson 2010).
