What?! I here you all say and to that I reply with:
As the first human spread out from their homeland of Africa the settled in areas that have different climates and terrain to the largely flat and dry conditions that we evolved for, evolution will take charge and the particular group of people who live in those areas will adapt slightly to better suit the environment they live in such as; changes in average height, lighter or darker skin pigmentation and muscle functions such as running or jumping being slightly superior in the majority of a race.
And there you have it the current [B]supported[B] reason for the different race's in the human species

Hello Mr. or Ms. Mistral. For someone who claims to defend evolution you have a very limited knowledge of it.
Here are some corrections to your statements:
1. Ancestors of humans did not evolve in an arid environment; it changed into that later and it our ancestors actually had to adapt to that change culturally.
2. Evolution doesn't take care of adapting people to changing conditions; you seem to be espousing a view here that would be more in line with the intelligent design model.
According to evolutionary theory, all mutations are completely random, most of them are completely harmless, a tiny minority is proves to be useful in some specific conditions, and an equally tiny minority is actually harmful.
3. While skin pigmentation does correlate with the exposure to sun, correlation is not causation. People have two ways of ingesting Vitamin D, one is through skin, the other is through diet. Hence, the Eskimos, who live in sun-deprived areas, are not light skinned - because they get their Vitamin D through diet, therefore random mutations of lighter skin were not an advantage.
4. That part about running and jumping has nothing to do with science - you seem to be projecting your own racial stereotypes here, but there's no scientific evidence to support it.
5. From a scientific point of view, there are no races at all, since human genetic variation within groups socially lumped as separate races is greater than genetic variation between them.
Therefore, if you were trying to support the scientific theory of evolution, your grade is F.
However, if you were trying to support the intelligent design and Christian creationism, then well done!
