You are missing the point, willfully or not: 1) Most humans literally could not drink cow milk because we simply never did until we started farming. Maybe you don't understand the time span? Yes, we can drink whatever and face the consequences, but the point is that certain people were more tolerant of cow milk and gained an evolutionary advantage. This wasn't dominant for thousands of years but became dominant, meaning the majority of humans were genetically different to humans before them. 2) Again, maybe you don't understand the time span? The jaw had gotten smaller, hence less teeth can fit. Why? Because our diet and eating practices changed over tens of thousands of years. 3) Evolution is the same process of any scale. The environment affects genetics, it isn't that hard to understand. It isn't "an example of evolution" it simply [i]is[/i] evolution as we know it .4) First, you can't be serious to think the eye is perfect, right? Our eyes adapted like everything else to help us survive in our environment, so did the hawk's eye, they are very different from each other so which is perfect? Answer: neither, and both; neither is perfect for every individuals, while both are most nearly perfect for the purpose of adaptation. It wasn't but 10,000 years ago the first blue eye was formed from a mutation. I don't mean to be rude, but were you being serious? Honestly, I can't tell.
