@iamsam82,
Jerry A Coyne, perhaps foremost Species expert and author of textbook of same name:
Are there Human Races?"
"...But from that sordid scientific past has come a backlash: the subject of human races, or even the idea that they exist, has become Taboo.
And this Despite the Palpable morphological Differences between human groups — differences that MUST be based on Genetic Differences and Would, if seen in Other species, lead to their classification as either Races or Subspecies (the terms are pretty interchangeable in biology)."..."
Sarrich and Miele
""[........]
Sarich and Miele then address Gould's race-does-not-exist mantra: "The basic reason Gould gives for his no-race position is this: 'Homo sapiens is a young species, its division into races even more recent. This historical context has not supplied enough time for the evolution of substantial differences.' (This from the man famous for his theory [with Niles Eldridge] of punctuated equilibria.)" They then go on to explain why Gould is wrong.
They looked at differences between human races, between males and females, and differences between primates—particularly chimpanzees and gorillas. **What is astounding is that there is greater morphological distance between human races than there are between the two chimpanzee species or between gorilla species/subspecies. **
That is, the differences between human Races are Real, they are Substantial, and they did not take millions of years to diverge. Humans, rapidly occupying every available niche after leaving Africa 50,000 years ago, has been under enormous pressure to adapt. To do this meant selection for morphological, pharmacogenetic, behavioral, and cognitive traits. Not only are there many human races, but there are at least as many races as there are ecological niches, and only humans can create their own niches with forethought. What this means is not only Are there human Races, but humans have evolved uniquely to alter there own cultures or ecologies, further increasing unique selection pressures....
Sarich and Miele explain: "Molecular data suggest that the two chimpanzee lineages separated around 1.5 million years ago; the comparable human figure is on the order of 15,000 years. In other words, the two chimp lineages are 100-fold older, yet show the same amount of variation. That is a remarkable result, the implications of which take a while to sink in. The implications follow this logic: Human races are very strongly marked morphologically; human races are very young; so much variation developing in so short a period of time implies, indeed almost certainly requires, functionality; there is no good reason to think that behavior should somehow be exempt from this pattern of functional variability.
