Hi Muriel, With all respect, I think talking about these two hunter/gatherer groups helps get to the crux of the matter. ie. 1. We are all hunter/gatherers who are essentially genetically similar and therefore have essentially similar dietary needs. This fits the Paleo diet and is the premise upon which it is based. These groups and others like them provide us with the only living examples of hunter/gatherers as a reference point. OR 2. As you imply, we have undergone some adaption. From this it may follow that there is enough genetic variety to consider different diets for different people and then the idea of "foreign proteins" and the Paleo diet becomes complicated. All the guff about genotypes and diabetic incidence are attempts to show this. Eskimos and Australian Aborigines have relatively extreme and limited diets and thus we can eliminate many variables by using them as a model. Watching how they adapt to and from their natural environment , can possibly lead to observations and generalizations about the population at large. On the other hand it may just complicate things :) Gary
