Brain Study Casts Doubt on Theory of How Human Intelligence Evolved. [Scientific American] "Using magnetic resonance imaging, the researchers obtained brain scans of 15 living great apes, four lesser apes, five monkeys and 10 humans--a sample larger than any used in the previous studies, which looked at the brains of deceased individuals. They found that, in fact, "the human frontal cortex was as large as expected for a primate brain of human size." That is, the size of the human frontal cortex is, relatively speaking, comparable with--not larger than--that of the great ape frontal cortex." The article goes on to speculate what several of the implications of this finding are. Interesting! 6:45:19 PM    comment   trackback []
