>>76473783 (OP)Generations of mal nutrition and low protein. if they got their shit together they'd catch up to whiteys 180lbs 180cm within just a couple of generations.
Which is consistent with any country or culture that suddenly gets access to sanitation and protein. Chinese are catching up fast to westerners in height and look at the koreans. Japanese just willfully starve themselves so it doesn't really count.
In primordial times europeans were as big as we are today, then when the ancient farmer groups started dominating average height shrunk. It got even worse when Romans spread their will because most "Romans" were scrawny slave DYEL/indentured wagies. When the industrial revolution came around and farming techniques improved in the 19th/20th centuries, europeans rapidly regained their primordial height within a few generations but many would have looked like OP before that.
For example the difference between BMI of north koreans and south koreans. It's epigenetics as another user said.
