Why are there different bodytypes for example (musclar or tall and thinner) and not an ideal bodytype, that everyone has?
In: Biology
Evolution made the human species adaptive to different possibilities. More food, less food, hot weather cold weather, war, peace, etc. By having all kinds of humans, we were able to adapt to many different places and situations over a long period of time. If we only had huge humans, they may have died out in periods of not enough food. If we had only weak, brainy humans, they may not have been physically tough enough to handle predators. Some of it is also random genes. A trait that is useful in one situation may fail miserably in another. Remember that evolution is not progressive. We are not leveling up to some perfect point. We have traits and variations that worked for some of our ancestors, and also some random traits.
