that is interesting. I was wondering whether the fact that their genes were so successful might have been partly to do with the active life style - no sitting around in offices in those days!Quote
I am going out on a limb here, but I would almost suggest the extreme stature and robust body builds are the outcome of a more paelo style, hunter gatherer physiology, subsiding off of high lean proteins, lack of anti-nutrients (few grains), and healthy seasonal variety and constant movement place to place. The teeth of many of these groups like Adena, and Archaics, had very low carries rate, up until the time of grain cultivation and agriculture of foods high in phytic acids were introduced. The late Dentist Weston A. Price, I believe still holds a credible case wherein excellently developed skulls, jaws, teeth and bone structure are found among groups who ate the traditional hunter gatherer foods, high in fat soluable vitamins, A,D,E,K,K2, calcium, phosphorus, and magnesium. I think the tall skeletons Jason Jarrell and Sarah Farmer have documented, are the leaders, shaman, warriors and hunters of these societies who attained physically impressive bodies through natural processes of excellent nutrition, and arranged marriages through social selective processes. I wouldn't rule out some underlying pituitary giants among some examples in European armies, and perhaps some of the extremely tall skeletons found in other parts, but even today the majority of people up to about 7 feet, or 7 ft 2 or 3, are not the products of pituitary diseases (See the NBA, only several players on the roster ever had Gigantism, most were healthy genetics).
