I'm not a Paleo dieter, but I am familiar with the gist of their claims. I do not understand how this study is a response to those claims. The 137 mummies studied are from "Individuals from ancient Egypt, ancient Peru, the Ancestral Puebloans of southwest America, and the Unangan of the Aleutian Islands were imaged." Of those we have 3 agricultural civilizations (Egytp, Peru, Pueblo) and one hunter gatherer (Aleutian). So 3/4 of the studied civilizations don't argue agains the basic Paleo claim at all. I can't see from looking the the links what the results from the Aleutian cohort were.
