    The discovery of a 54 million year old primate skull looks set to challenge long accepted ideas about why our brains are so large.
    By scanning a 54-million-year-old skull roughly the size of a walnut, scientists have created the first virtual 3-D model of an early primate brain, a new study says.

    Surprisingly, the model suggests that primates (such as lemurs, monkeys, apes, and humans, among others) might have evolved larger brains as a result of the need to move quickly from tree to tree—not, as commonly assumed, to hunt for fruit or navigate within a single tree
