Compare the Brains
LB1 and Pan troglodytes
And how did LB1's brain compare to that of a chimpanzee? While the
two brains are about the same size, they differ dramatically, the
team found. LB1's has large temporal lobes, which in people are
linked to hearing and understanding speech. More significantly, LB1
has highly convoluted frontal lobes, the region just behind the
forehead that is associated with higher cognition. Altogether, the
findings support the notion of advanced intelligence in a small
package. This flies in the face of current dogma, which maintains
that increased intelligence only comes through increased brain size.
