I love this video because it describes why this race and iq business is very silly from a genetics point of view:
1) Genetically speaking, there is no such thing as "race" in humans, (or "subspecies" as alt-righters refer to it) for several reasons:
a) We simply haven't been around long enough for such speciation amongst ourselves to happen. Evolution places us at 200,000 years old as a species, which is but a blip in terms of evolution.
b) Even worse than this, we are ALL descended from a very small population of humans, probably just a couple of a thousand, as the group of humans on the continent had been drastically reduced to that size by some cataclysmic event some 70,000 years or so....ALL of us, without exception, even the aborigines of Australia. It was after this that the out of Africa movements from our own "group" started happening. So its a 70,000 year window for us to evolve away from each other in order to give rise to biological races.
c) Even presuming there had been some speciation before then, it has vanished from the genetic record because all of us who survived were from that tiny group 70,000 years ago that was closely "related" lets say.
d) There have been no genuinely isolated human groups during this short time due to the constant migratory impulse of the homo sapien sapien which has always given rise to waves of migration all over the world throughout. No genes have been completely/perfectly isolated.
e) There are no clusters of genes that can define biological race. ie. traits you can say belong to only one group (100% of the group has them) and only them (no others have them). Even the ones we are most likely to point out, eg East Asian slanted eyes. European blonde hair/blue eyes, white skin, brown/black skin fail the test because none of them belong exclusively to anyone group (google blonde, blue-eyed Aborigines or Khoisans to see "East Asian" eyes) or to every single member of any group to the exclusion of others so that you can say that THAT is the defining trait of that race vs another race or vs all other races.
-They are also arbitrary. These are very superficial traits corresponding to certain large geographies but you could use less visible but more fundamental genetic traits to create WHOLLY different "races".
f) The diversity: There is more genetic diversity between African "black" groups than between "Africans" and "Europeans" for example. So pygmies and the Tutsi and Some other bantus, Nilotes, etc probably qualify much more as "races" than "Africans" and "Europeans" or "Blacks" and "Whites". Yet even in that case, the difference is negligible and this is almost unique to humans (the tiny amount of diversity) or at least is rare compared to nearly all other species.
-Again, humans just barely arrived on the evolutionary time scale and were reduced to a tiny population of East Africans 70,000 years ago. I've seen it said that any two of us are more closely related than two apples you pick up at a store. That's what they discovered when the entire human genome was mapped in the early 2000s.
2) Linking IQ to intelligence per se is controversial
3) Even more, going further to link this iQ-intelligence thing to race (a biologically non-existent thing) is problematic to say the least.
Another video you can see is this:
Linking intelligence to race using IQ is a highly problematic thing to attempt from a scientific perspective because of how nebulous both "race" and "intelligence" are, no matter what you think of the IQ test's relation to innate intelligence is.
