No — there aren’t “stages” of evolution, that’s a misconception. Evolution doesn’t lead anywhere in particular. We like to think of humans as being at the “top” of something, but that’s a product of anthropocentric bias. All that matters is suitability for the environment.
Humans are suited to living in cities, yes, but chimpanzees are better suited to swinging from trees.
Humans can kill a bear with a gun, but in a 1-on-1 fight, without the human having the benefit of tools, the bear will win every time.
Humans can’t swim at high speeds or live underwater under the crushing pressure that some aquatic creatures tolerate.
It can be argued that insects are more evolutionarily successful than primates, that plants are more successful than animals, and that bacteria are the most successful of all. (What about viruses? Are they even “alive”?)
As regards humans and “races”: What differences? There are very few differences between “races,” mainly cosmetic. The concept of race is sociological. The modern understanding of race didn’t exist until a few centuries ago. Perhaps in a few decades or centuries more, “race” will no longer exist.
You’ll find more populations of darker-skinned people in equatorial latitudes which helps ward off sunburn and skin cancer — that’s one of the main differences, but it’s a small one. Nothing suggests that darker-skinned people are on a lower or higher stage.
