-[This is a pretty good book](https://www.twelvebooks.com/titles/charles-murray/human-diversity/9781538744000/) about things we know about some ways in which people are taxonically different from each other! Honestly, I feel like I already knew most of this stuff?—sex differences in particular are kind of _my bag_—but many of the details were new to me, and it's nice to have it all bundled together in a paper book with lots of citations that I can chase down later when I'm skeptical or want more details about a specific thing! The main text is littered with pleonastic constructions like "The first author was Thisand-Such" (when discussing the results of a multi-author paper) or "Details are given in the note<sup>[n]</sup>", which feel clunky to read, but are _so much better_ than the all-too-common alternative of authors _not_ "showing their work".

In the first part of this blog post, I'm going to summarize what I learned from (or was reminded of by) _Human Diversity_, but it would be kind of unhealthy for you to rely too much on tertiary blog-post summaries of secondary semi-grown-up-book literature summaries, so if these topics happen to strike your scientific curiosity, maybe you should skip this post and [go buy the source material](https://www.amazon.com/dp/B07Y82KNS1/)—or maybe even a grown-up textbook!
Another mechanism of recent human evolution is _introgression_: early humans interbred with our Neanderthal and Denisovan "cousins", giving our lineage the chance to "steal" all their good alleles! In contrast to new mutations, which usually die out even when they're beneficial (that 2<em>s</em> rule again), alleles "flowing" from another population keep getting reintroduced, giving them more chances to sweep!
+[TODO: association studies "trained" on one population don't perform as well against a "test set" from another population]
+[frequencies of SNPs for schizophrenia correlate well for subpops on the same continent (p. 187–8)]
+
+[table p. 192]
+
+[sickle-cell, lactase persistence]
+
+[Tibet, Peru, Ethiopia all have high-altitude adapatations, but they're different adaptations, p. 198]
+
+The third part of the book is about genetic influences on class structure!
+
+[p. 212-4: A + C + E model and comparing identical and fraternal twins (different from twins raised apart)]
+[ACE model assumes no assortative mating, which leads to an underestimate of A: because it makes fraternal twins resemble each other for non-environmental reasons]

conservatives complain about low-time preference ppl having too many kids—but from a evolutionary perspective, they're more evolutionarily fit
