Negative Positive
Title: Diamond misses the obvious
Review: The obvious reason why Europeans and Asians developed such advanced societies while other did not is indeed because of geography. Unfortunately for Diamond, it's not because of guns, germs, and steel. It's because of cold winters. Cold winters mean limited food. Therefore, those members of the tribe who did not possess the intelligence and foresight to prepare for a period of no food---died. China, Japan, Korea, America, and Europe get cold. Australia, Africa, Central and South America do not. The less intelligent genes don't get thinned out, because there is an abundance of food year round. That's not racist or biased, just common sense.
