Sorry to tell ya bud, but there are races, but they aren't what you think. Races basically mean tribal origins. Humans are a tribal species, so while races don't mean separate species, there is some cultural and biological bias introduced into the system when you separate them into tribes for a long enough duration. Its not enough and we haven't been doing it long enough to introduce speciation, though the biases are there, asians are shorter, white guys sunburn faster, black dudes get sickle cell anemia more often, etc. There are adaptations which are genetic in each tribal subgroup. Native americans are very vulnerable to fermented alcohol, etc.
