Human Evolution. . .?

My husband and I are having a disagreement about how people ended up with dark/white/fat/skinny skin. We were having a discussion about the science view of how humans came around. In the time line of what we can determine of human existence, why/how did people get different skin pigments and body sizes?

The reason for skin color is of course related to the sun. As people began to move north, their skin became lighter because you do actually need some sun light. It is this sunlight that creates vitamin D in your body (which of course you can get from supplements these days, like vitamin D milk). So, if you are dark and live in an area with very little sun, you can not make vitamin D as well. The lighter your skin became, the healthier you were (better able to make vitamin D).

As for size, people started to become bigger around the same time we began to farm. People in cooler climates tend to have larger bodies than people in warmer climates. It gets really complicated actually...

well This link will answer about the different skin colors.

A lot of the fat, thin, tall, short come from our diet.

The original human genetic code held genes that would eventually result in the many races and genetic differences we have today. Geneticists can actually trace all mankind back to the Mesopotamia region, where the Bible indicated man originated.
