complete horse shit. you can literally measure intelligence across all species by their brain size. compare a chimp to a bird. or a nigger to a white man. doesn't matter. also the chinese are the smartest human race currently. they also have one of the oldest cultures and have survived harsh conditions. brain size apparently is linked to living in harsh conditions for long periods of time. people who live in a sunny equator and have plenty to eat and kill year round have the smallest brains. those who lived in places where the weather is cold or the food is scarce have larger brains. this is because they needed the intelligence to survive.
