How does natural selection affect animals

Animals are affected by Natural Selection because Inherited characteristics affect their likelihood of survival and reproduction.

Natural selection is a process known as the survival of the fittest.

It affects animals because only those who have adaptations to their environment survive and pass on their genes to their offspring.

For example. Giraffes in Africa has in natural selection has a long neck. Through natural selection, only giraffes with the long neck survived and passed on that trait to their offspring.

Natural selection is just making sure only the strongest survive to reproduce
