Any differences would be slight. It takes 10-40,000 years for a genetic mutation to become fixed in a population and conditions have to be consistent during this time (ie. not still migrating and changing diet).
The genetic variations in the last 70,000 have been extremely rare and we are only seeing partial adaptions (ie. lactose tolerance in a portion of the population).
As we only started moving out of Africa 60-70,000 years ago, the paleo diet equally applies to everyone. There might be slight tolerance differences in populations, but the basic principles apply equally across the globe.
The "Seven Deadly Sins"
• Grains (wheat/rice/oats etc) . . . . . • Dairy (milk/yogurt/butter/cheese etc) . . . . .• Nightshades (peppers/tomato/eggplant etc)
• Tubers (potato/arrowroot etc) . . . • Modernly palatable (cashews/olives etc) . . . • Refined foods (salt/sugars etc )
• Legumes (soy/beans/peas etc)
