Hi William, The logic is flawed but it is based on comparisons with modern bones. The incorrect assumption is that we eat and live at least as well as Paleolithic humans. By that thinking, they have erred on the safe side. This paradigm is further supported by Neolithic evidence of the "nasty, brutish, and short" lives reported by historians. Of course, the latter groups were deeply invested in agriculture. There is North American evidence from the Dickenson burial mounds showing significant reductions in bone density, reduction in stature, and other signs of disease-driven bone damage during the transition to agriculture. The cool thing about this evidence is that it showed that the deeper investigators excavations into the mounds, the further they went back along the line of forebears. The evidence clearly showed that HG had strong healthy bones but their descendants who undertook agriculture suffered significant reductions in bone health because of their dietary choices.
