Simplying googling it returns a couple of papers.
I was first exposed to the idea in “Farewell to Alms” by Gregory Clark (somewhere around page 55)
Thanks for the clever insult, though. [/quote]
Don’t take it too personally. I just get tired of this neoteric cliche that modern agriculture is some kind of a malevolent, insidious force that is secretly destroying the planet.
I think it is a fairly well established fact that with modern agriculture practices have come human stature increases. Maybe you can successfully throw out the ol’ tried and true “correlation does not prove causation” rule of thumb…I dunno.
I do know or at least am rather well convinced that practically anywhere you go on this globe and find hunter-gatherer societies you will find people of relatively small stature. Go to the Amazon or New Guinea here in modern times or to many, many different places in the not too distant past such as the Inca, North American native of the 18th - 19th century, Mongolia, rural Siberia and China, the Himalaya, etc. - any place where a modern agricultural system is not or was not in place and inevitably you will find short people as a general rule.
Do not point to the exception to the rule societies in Africa where tall people predominate because if you do I’ll take you a few miles up the road from there and introduce you to populations of pygmies.
On the flip side I can anthropologically take you to the societies where tall people exist in great numbers and you will typically end up with societies that have practiced “modern” agriculture for quite some time now.[/quote]
You are wrong.
There is lots of evidence that with the neolothic revolution people got smaller and had lots of diseases that can be attributed to malnourishment.
Also, there are lots of genetic markers that get rarer the later agriculture was introduced into a society whereas others that make the digestation of grains more difficult get more prevalent.
We are rain forest primates, we never evolved to eat grains so some genetic adaption was necessary and is still not completed yet.
Even today, whenever some indigenous group like the American Indiands the Inuit or the Aborigines are confronted with our diet massive diabetes and CHDs are the inevitable result around 20 years later.

Abstract The increase in the Neolithic human population following the development of agriculture has been assumed to result from improvements in health and nutrition. Recent research demonstrates that this assumption is incorrect. With the development of sedentism and the intensification of agriculture, there is an increase in infectious disease and nutritional deficiencies particularly affecting infants and children.
Declining health probably increased mortality among infants, children and oldest adults. However, the productive and reproductive core would have been able to respond to this increase in mortality by reducing birth spacing. That is, agricultural populations increased in size, despite higher mortality, because intervals between births became shorter.
