The evolutionary changes occurred in giraffe, they developed long necks and rest of its body also became massive. So as the nerve cells are also long.This made the giraffe to respond very slowly to the outside environment. In contrast, rats have very short nerve cells (neurons) ,their response to stimuli is so fast.Hence function of the cells related to their size
