Frontal Lobe - Evolution

Evolution

For many years, many scientists thought that the frontal lobe was disproportionately enlarged in humans compared to other primates. They thought that this was an important feature of human evolution and was the primary reason why human cognition is different from that of the other primates. However, this view has been challenged by newer research. Using magnetic resonance imaging to determine the volume of the frontal cortex in humans, all extant ape species and several monkey species, Semendeferi et al. found that the human frontal cortex was not relatively larger than the cortex in the other great apes but was relatively larger than the frontal cortex in the lesser apes and the monkeys.

Famous quotes containing the word evolution:

    The evolution of humans can not only be seen as the grand total of their wars, it is also defined by the evolution of the human mind and the development of the human consciousness.
    Friedrich Dürrenmatt (1921–1990)

    Historians will have to face the fact that natural selection determined the evolution of cultures in the same manner as it did that of species.
    Konrad Lorenz (1903–1989)

    What we think of as our sensitivity is only the higher evolution of terror in a poor dumb beast. We suffer for nothing. Our own death wish is our only real tragedy.
    Mario Puzo (b. 1920)
