Obviously there are structural differences to underlie the rnormous intellectual differences:-"To learn more about the STAP, the researchers looked at brain scans of 177 people and 73 chimpanzees—analyses revealed that while clearly present in all the human scans, it was barely present in any of chimps. The team notes that in the right hemisphere, the groove is in a part of the brain involved in facial recognition and in figuring out the motives or feelings of other people. In the left hemisphere, the groove runs through a part of the brain very clearly associated with language skills.-"The human brain is approximately three times as big as a chimp's, yet finding functional differences in brain structure has been difficult to pinpoint. One structure that has been seen to be different is Broca's area, which is known to be important to speech. It is smaller in chimps which would seem to make sense as their speech capabilities are far less complex."-http://medicalxpress.com/news/2015-01-brain-groove-unique-humans.html
