There are many other factors like bone structure (which is also dictated ultimately by environment) and the year-round warm weather that seem quite clearly to contribute, but it would be a digression and wouldn’t really be necessary to illustrate the point.
Disagree, it illustrates that point that saying “Kenyans are more likely to be great distance runners” is in fact more accurate than saying “People whose ancestors spent uncommonly large amounts of time at great elevation with less oxygen [are more likely to be great distance runners]” since the former doesn’t have the burdensome detail of assuming a particular causal mechanism.
I’ll correct that. Was probably in the course of typing several replies on different parts of the subject. Bone structure gets detected by environment, but it in itself isn’t.

Bone structure is an environmental factor? What?
