But the whole argument requires picking and choosing your stance, so you're choosing to base it off an average family or four in the US as opposed to a generic "hunter-gatherer of North America," apparently from the north/northwestern region. There were periods long before they could hunt large game, and there are groups today, such as the Inuit, that have extremely limited traditional diets in regard to biodiversity if you don't include the influx of modern foods.

I'm just taking exception to the often-stated but not well-defined stance that hunter-gatherers of specific yet undetermined locations and time periods had such impressively diverse diets compared to modern times.
