A large sample is certainly needed to get round false positives.

[...] The required sample size is of order 100s, or roughly a million in the case of cognitive ability."<br /><br />IIRC that estimate was revised to about 300,000 using fancy compressed-sensing techniques. Full genomes may not be needed to get most of that. <br /><br />To identify ancestry, looking at only a few dozen of the right genes can determine actual ancestry better than genealogical records. A sample size of a few thousand with standardized test scores would be good enough for practical purposes, but really no amount of evidence will convince those who are not already convinced by data sets such as the NLSY which cover over a million people over decades. H&M's The Bell Curve really closed off all plausible objections to the gene-intelligence link both within and between populations, but the blank-slatists and diversity cheerleaders just closed their eyes, stuck their fingers in their ears and went: "Na na na ... I can't hear you! Heretic! Meanie!" and so forth in that vein.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4624586630299165335.post-21702548096347129022016-03-19T01:36:58.669+00:002016-03-19T01:36:58.669+00:00Nice paper; I would buy them a drink.

It would fit in with current findings on system integrity, that bodily health and a good brain share common common genetic pathways, and are more resistant to wear. So, it would be more likely that that brightest survived. How advanced were those civilisations? The Incas had some blind spots. China they weren't.

I wonder whether the huge death rates from Old World diseases during and after the conquests were somehow selective against IQ. I don't know enough biology to begin to suggest a mechanism for that. deariemenoreply@blogger.comtag:blogger.com,1999:blog-4624586630299165335.post-10106530155677794382016-03-15T23:18:07.308+00:002016-03-15T23:18:07.308+00:00I am happy to find your way of writing the post.
