Well, maybe I'm confused. To me, "paleo" refers to that which was done by our primitive ancestors, meaning the more recent members of the Homo family, at least in the context that we use "paleo" in this list. There is no value whatsoever in comparing us to pelicans; they're not even in the same family (or genus or whatever; please pardon my ignorance of taxonomic terminology). Different animals have different diets and different requirements. Until the day archaeologists unearth defensible proof that the majority of humans of a million years ago were doing that, and that they did it for long enough for it to have become included evolutionarily, I'm not going to be convinced that the idea has any business being called paleo or being discussed in a forum that is supposed to be devoted to paleo diet and issues. Sorry. Take care, John Pavao ---------- I don't think there's anything unpaleo about intestinal cleaning, I've read pelicans give themselves colonics.
