Answer: To be able to reach the food they need.
Explanation: Giraffes feed off of high trees. In order to get that food, they were forced to naturally adapt to the height of the trees. Natural selection is a process where organisms that are better adapted to an environment will survive and reproduce. This means that the advantageous alleles of this variant organism are passed on to offspring. Over many generations, the process of natural selection leads to evolution occurring.
