The theory of evolution is that organisms have evolved over time, and have changed to better match their enviroment. One example of evolution is the skeleton of a ape, because over time the ape bones got more upright so instead of walking in all fours they could just walk in two feet. This supports evolution because it shows that ape species evolved over time to be more efficient, and to abel to better adapt to the enviroment by just standing on four legs. It also shows that ape have gotten more similar features to the ones of human beings over time. Another example of evolution is the skull of a monkey, a monkeys skull has a different shape than the one of a humans, but how younger the species a monkey is the more it looks like a human skull.
