And potatoes.
Part slavic myself...
Agriculture was a hard life that was practiced pretty much as shown in that pic from its beginnings until very recently. My greatgrandmother, bless her heart, was a stout 4’x5’x4’ and strong as an ox. Hoed potatoes like that couple times a week....Her son used a small tractor but she wielded the hoe.
When I made the part environment (including exercise and diet), part selection comment was partly motivated by a Scientific American article I read a couple of years ago. The article described differences in Mexican Indian skeletons from the periods before and during the Mexican takeover.
In comparison with earlier skeletons, those of the Indians enslaved by the conquistadors had two noticeable features: first, heavier bones, which was attributed to heavy forced labor, and second, worse teeth, which was attributed to a diet that had more corn and less meat. Clearly, these factors were environmental, not genetic, because the pre-and post- conquest periods were adjacent in time.
