It seems to me that you mistake the end-goal of evolution to be complex, and human-like. Evolution isn't solely about increasing complexity. Humans aren't the pinnacle of evolution. Apes aren't becoming more like you and I because they don't need to. Here's a scenario: Two groups of apes, one lives deep in the forest, the other at the edge. Over time, (10 thousand years, lets say) the forest monkeys keep living in the forest, and only the ones that are very good at climbing trees and grabbing fruit and are thus more healthy. This makes them desirable to female monkeys. They breed more. The ones bad at climbing don't mate, because they are sickly, or too muscular to climb well. They are not attractive to the other sex. Over 100 generations, only the monkeys good at climbing make more monkeys, which are, typically good at climbing. These are the concepts known as Fitness and natural selection. One trait was better ADAPTED and thus a benefit over another. It won the competition and stayed around. The other (non-climbing) wasn't aiding in the survival of the monkeys, so that trait wasn't passed on as often as climbing, agile monkeys. Let's look at the other group, the forest edge monkeys: They can find food both in trees and on the plains away from trees. Over 100 generations, the forest shrunk and they had to compete with the climbing monkeys deeper in the forest, this was a battle that they wouldn't win, all the fruit was gone, taken by the better climbing monkeys deep in the forest. So they stick to food on the plains. But the grass is tall, so they learn to stand up and look over the grass. Now the tall, strong monkeys that can see danger, and carry lots of food to the family are the ones that are healthier and sought after. The short agile monkeys are at a disadvantage and don't breed often. This physical characteristic eventually dies out. Over millions of years, this group of monkeys will grow very tall, be able to run long distances, and ditch all the body hair, because it's hot in the sun. They become 'human'. The forest monkeys stayed short, agile, strong, and excellent tree climbers. WHY? Because they didn't need to. The monkeys that were good at living in trees a million years ago had the same body shape as today because it's perfect for the monkeys lifestyle, climbing trees for food. So you can drop that idea that evolution is a downloading progress bar, with the 20% complete, or 80% monkey nonsense. Evolution is not a conveyor belt to being human. | |||
