Our genetics are identical to our ancestors of 20,000 or 40,000 years ago (or so I've read). The idea that we should eat the diet of our ancestors stems from the fact that evolution chose certain genes to fit a certain diet. From that argument then 20,000 years back would be the "ideal" paleoithic diet.
This means (surprise surprise!) no wheat or any other grains (yes, including such "healthy" staples like brown rice, perhaps the most nutritionally overrated food), no dairy, legumes, and certainly no refined sugars!
The localization issue is another story. I myself haven't looked into the dietary variance across different regions.
