Welcome! I find the more scientific support for primal/paleo living fascinating, though somewhat beyond my grasp. I think one of the reasons that Mark doesn't link to more studies and papers is that there simply aren't any. Or at least very few. There are tons of blogs out there that may link to more studies etc though. You can find some of them through the forums (I think there are some in a sticky thread in Meet & Greet, and the Resources and Research threads usually have links to good information).
