The map is here. What it shows is that the world map of human races corresponds with the world map of Mean Average Temperatures. See, race begins and ends with place. The anthropologist Nina Jablonski is a leading proponent of this way of thinking…
We are always looking for the universal human. Plato saw the guardians as this kind of subject. Hegel saw it as the civil servants. Marx, of course, saw it as the proletariat. But the universal subject is actually not a product of social history, but an accident of natural processes. This is why Stephen J. Gould got it right when he wrote that humans are “contingently equal.” By this he meant: We are equal not because of some design or purpose but by the accident our newness. Humans are really very similar and very new (250,000 years is even less than a blink in deep time). You will find more genetic differences within a community of chimps than humans from any part of this world. The universal subject has only just arrived and it is all of us—the human species.
Indeed, I think our ability to cooperate with strangers (the true genius of human socaility) may have something to do with the speed with which we spread around the world, our newness, and general genetic closeness rather than a consequence of cultural evolution and the social markings that Peter J. Richerson and Robert Boyd discuss in their important book Not by Genes Alone: How Culture Transformed Human Evolution. We have long to go before we reach the noon of the universal subject
