Well, I just give some examples. Here we have a value that represents molecular genetic data, and I emphasize that because this something you screen using DNA techniques, so there is no subjective values that people put on other kinds of traits, like skin color. And the other flip side to that is that 85 percent of the genetic differentiation found in humans is just from the fact that we are individual. So it is saying that there is genetic differences among different human populations, but it is still saying the vast majority of the differences found in the human species as a whole is just due to the fact we are individual. And even in that small region, they are already up to about a ten- percent differentiation.
Humans are fifteen percent globally.
But then all these other species, like the impala just within Kenya, showing as much differences between their populations, as humans do across the globe. Coyotes in North America are twice as differentiated among their populations just in North America, as humans are around the world. And where other organisms that do have subspecies like the wolf are much more differentiated. So even though we attribute a lot to our differences, when we actually quantify those differences objectively we find out humans are a very homogenous species, not to say we don t have genetic diversity, we have a lot of it, but it is mostly at the individual level. This is based upon looking at a hundred molecular markers scattered throughout the human genome, giving you a good indicator or the overall level of differentiation and this diagram puts it in a two dimensional framework.
