I know natural selection. It can be through breeding or cell mutation? Or how else would the genes be eliminated? is 7,000 years long enough for that? Jews also have a very low abuse rate. alcohol was around since the dawn of civilization in Sumeria. To trace the orgins of alcohol in different parts of the world and to say that Northern Europeans weren't genetically touched in the past by ancestors that drink alcohol...it seems far fetched...but if you could map that all out for me It would be interesting....lol just kidding you don't have to do that
Chinese as it seems have had alcohol before recorded history. They have a genetic component the lowers their tolerance to inebriation. Native Americans have a similar intolerance but somehow have a high alcohol abuse rate while the Chinese have a very low one. that's one flaw anyway
There is the culture in your home and there is the culture in the society around you. You might of had friends who drank in high school or college...the messages you got in addition to the influences at home.
