1. That there are population (not race, these are not the same thing and only ever overlap by happenstance) differences in some critical traits for survival is old news. These traits are few and far between and have been the subject of extremely strong selective pressure. They're also subject to evolutionary convergence. For this reason they can't be a good proxy for classifying populations phylogenically, even though they do come up in medicine. Also, because of the very one-dimensional and extreme selective aspect of it, it is highly dubious that very complex traits (let alone undefined traits like "intelligence") could be involved.
2. That you lump up artificial selection for a single purpose and natural selection (which Darwin specifically coined as opposed to the artificial selection we do on animals) shows you have a very limited understanding of how, well, evolutionary genomics works. You can't treat selective breeding the same way you treat natural selection. You need to look up basic concepts before we have a reasonable discussion.
3. You keep thrashing Saini but you haven't addressed the fact that her books have received inputs and feedback from many prominent people in the field. I asusme you're not a specialist so surely your first reflex should be to assume the people she's thanked in the foreword know what they're doing as their daily job.
