Fortunately, we all know that correlation does not always mean causation. At least we should know that.
**Tom **has it right. There is nothing inherently “bad” about the idea that some populations are going to be better at certain sports than others. I would be surprised if it were not so. But you have to define the population you are talking about, make sure that is in, indeed, a genetically distinct population, and then take some scientific measurements. That is, random, controlled experiments. Observations we make in everyday life can be strongly suggestive, but not scientifically conclusive.
You can call it whatever you want, but it doesn’t change the underlying reality, which is that sprinting ability is not distributed randomly among the world’s populations.
