An anthropologist at FSU has discovered an explanation of brain evolution from our ancestors to the modern human. There are two significant features that are different. The first feature is a "persistent metopic suture," or unfused seam, in the frontal bone, which allows a baby's skull to be pliable during childbirth as it squeezes through the birth canal. The second feature is the fossil's endocast, or imprint of the outside surface of the brain transferred to the inside of the skull. He concluded this by examining the Taung skull and many other human and ape skulls.
