Human subspecies don't exist. Unlike many animals, modern humans simply haven't been around long enough or isolated enough to evolve into separate subspecies or races. Despite surface appearances, we are one of the most similar of all species.
Race has no genetic basis. Not one characteristic, trait or even gene distinguishes all the members of one so-called race from all the members of another so-called race.
That's because most human variation falls within, not between populations. About 85% of all genetic variation can, on average, be found within any local population, be they Swedes, Kikuyu, or Hmong. About 94% can be found within any continental population, consistent with what the Rosenberg Science study found. In fact, there are no characteristics, no traits, not even one gene that turns up in all members of one so-called race yet is absent from others.
http://www.pbs.org/race/000_About/002_0 … -01-02.htmThe earliest hominids evolved from apes about 5 million years ago, but modern humans (Homo sapien sapiens) didn't emerge until 150,000-200,000 years ago in eastern Africa, where we spent most of our evolution together as a species. Our species first left Africa only about 50,000-100,000 years ago and quickly spread across the entire world. All of us are descended from these recent African ancestors.
Many other animal species have been around much longer or they have shorter life spans, so they've had many more opportunities to accumulate genetic variants. Penguins, for example, have twice as much genetic diversity as humans. Fruit flies have 10 times as much. Even our closest living relative, the chimpanzee, has been around at least several million years. There's more genetic diversity within a group of chimps on a single hillside in Gomba than in the entire human species.
Domesticated animals such as dogs also have a lot of genetic diversity, but this is mostly due to selective breeding under controlled conditions. Humans, on the other hand, have always mixed freely and widely. As a result, we're all mongrels: Eighty-five percent of all human variation can be found in any local population, whether they be Kurds, Icelanders, Papua New Guineans, or Mongolians. Ninety-four percent can be found on any continent.
