Charles Darwin stated:

At some future period, not very distant as measured by centuries, the civilized races of man will almost certainly exterminate, and replace, the savage races throughout the world. At the same time the anthropomorphous apes . . . will no doubt be exterminated. The break between man and his nearest allies will then be wider, for it will intervene between man in a more civilized state, as we may hope, even than the Caucasian, and some ape as low as a baboon, instead of as now between the negro or Australian and the gorilla.

Sadly, if HBD is correct, I think there probably will be natural selection favoring higher IQ populations, in fact it’s already happening.  In sub-Saharan Africa, we see the more primitive cultures like pygmies and Bushmen losing more and more territory and their populations declining.

In the United States, we see Hispanic gangs ethnically cleansing African Americans from urban regions.

In the Middle East we see Israel has very cleverly got America on their side, and thus are gaining more and more territory from the lower IQ Arabs, and neocon wars are causing many of the Arabs to leave the Middle East and move to Europe, and so HBD would predict that the average IQs of European countries will be dragged down to where they are no longer military powers who can defend themselves.

If HBD is correct, I think what ultimately will happen is that the highest IQ ethnic group in each of the three traditional races of anthropology (Negroid, Caucasoid, and Mongoloid) will replace the lower IQ ethnic groups in each of the those races, and so each macro-race will become ethnically homogeneous.

And then in the final stage, I think we will eventually get a war between three macro-races themselves.  I predict this war will be horrible, with millions of people crying on the street.

And when it is all over,  I predict the only survivors will be Northeast Asians and their kids will read in anthropology books about all the other races that used to exist.  A few members of these races will be brought back to life through cloning, but they will be confined to zoos, where little East Asian children will safely point and laugh.

Hopefully my predictions are wrong, but if they’re not wrong, hopefully, they will unfold long after I’m dead.  I’m in my 30s.  If I’m lucky I’ll live until my 80s, but sadly, a lot can happen in half a century.
