Evolution of Intelligence

Why does a species evolve to speak? What causes something evolves to the point where it can think, “hey this fruit is too high maybe I can use these rocks to get it down”.  Like with many things a credible theory for why would be evolution. If we look on our branch we will find Chimpanzees.  Chimpanzees evolved from a common ancestor and for all purposes are our sister species.  Like humans there is more to what they do then eating and mating. They have figured out how to communicate with each other, they work together to accomplish goals. They can stop and analyze a situation rather then just jumping in. they make use of tools in their surroundings to help them complete their goals. They care what other members of their species think about and fall into ranks under who has the most food or best ability to get food. And they are quite capable of using deception to gain the advantage over other members of their species. At the moment it is unknown exactly what caused us to develop the way we did and what caused our relatives to evolve the way we did. But what this does show is that intelligence is a evolutionary trait and not something we just have. It shows that something must have gone right in our branch’s past to allow us to be how we are today.
