Dr. Eugene Morin of Trent University has proposed that humans evolved from Neanderthals rather than both homo sapiens and homo neanderthalensis evolving from a common ancestor. The professor believes that humans were an adaptation to the harsher climates of prehistoric Europe.

Young chimpanzees were found to outscore human university students in short-term memory speed tests, although their results were no more accurate. The scientists believe that we may have lost some of our speed in memorizing environmental cues in return for developing language. They next plan to put the chimps against children, theorizing that some of the student's speed deficit might simply be age.
