Loren Cordain's recent post was quite interesting. However, there was one statement that puzzled me: "Therefore, calories derived from hunted animal foods remains relatively constant in all hunter gatherer societies regardless of latitude." It was my understanding from previous postings that the studies show a reasonably large range in this variable. Is that not the case? With regard to the relationship with latitude, I wonder if the relationship with respect to role of fishing is somewhat skewed because the sample may be heavily represented by very high latitude HG groups that rely greatly on fishing. I would suspect (and perhaps Loren can answer this) that the sample from the Ethnographic Atlas largely contains HG groups in the tropics and the very high latitudes, since historic HG groups have been largely eliminated from the temperate zone.
