That doesn't change the fact of evolution. You are denying a reality. Humans are changing, evolving. This change takes places over thousands of years, so we don't see it on a superficial level. Intellectually, humans are also changing. It's happening. The fact that it may be more protein in the diet that causes people to be larger does not negate the fact that we are evolving. That's only one way we are evolving.Humans are getting larger because there's more meat in their diet. Go to a country where they still eat mostly corn and beans (Mexico) and you will see how small the people are, especially the Indian women.Humans are evolving now. Monkeys are probably also evolving. Evolution takes places over thousands of years. For example, humans are larger than they used to be. Go to an ancient site and see the size of doorways, beds, clothing, etc. Humans are getting larger, physically.
If anything, humans are de-evolving. Evolution happens when groups of a species are separated and allowed to "evolve" on the traits that help them survive in their specific environment.
In the modern age, all humans are connected since travel is so easy. The mixing of human groups that were separated for thousands of years is taking away the uniqueness of each group. Once the human race is nothing but a bunch of mulattos, there will be no diversity and no unique qualities to help humans survive.
