It’s just that we’re out of excuses now for race differences in intelligence. And this study is clear and large enough with enough safeguards against bias and outcome determinacy, that there just is no point.
Race isn’t skin deep. For all intents and purposes we were speciating by geography (continent/climate) until the agrarian revolution. But we are hyper-adaptive including sexually hyper-adaptive so despite morphological differences that would cause other species to resist hybridization, humans are less likely to resist hybridization and continue speciation.
