Human Evolution Extended

We see large and small people, both in height and weight. Some people have incredible gifts like impressive athletic ability or heightened senses. Sometimes, these things can be trained but other times you either have these gifts or you don’t. This brings about the old “Nature vs Nurture” Debate.
While trained gifts are impressive, a person with natural-born traits, who trains the same as someone born without, will often trump the one without due to their natural abilities. Yet one could pass on those natural abilities as well as things like mutations, skin color, and much more. Yet there are many gifts humans have that they do not even realize.
