HUMAN EVOLUTION
            
             Is it possible to reconstruct the past? This is the question anthropologists and other scientists have been trying to answer for decades. Mammals are curious creatures and it is this curiosity that causes humans to want to know our past. Most of the information known today has been discovered within the last thirty years. Thanks to technology, funding, and pure luck, we now know more about our origin than ever before.
             One of the first discoveries was that of a skull by Raymond Dart. He declared this skull to be part of somebody who was a relative of humans. He determined that this creature walked uprights, which led against popular belief – very few supporters.
             In 1959, Louis and Mary Leakey found a "teenage" male skull. They found the skull beside a lake, leading them to believe that the rest of the body got washed away. Sediments and volcanic ash that allowed for argon dating preserved the skull. The skull was dated back almost two million years.
             Charles Darwin once said, "Humans are most closely related to African Apes." He determined this by comparing the blood proteins of thirteen different primates. He also concluded that chimpanzees are our closest relatives and that we branched off from one another approximately four to five million years ago.
             Chimpanzees are similar to humans, yet they are not identical. We both have fingernails and personal fingerprints, but humans are relatively hairless, we walk upright, use language, and have bigger brains. Chimpanzees attack with weapons, but when an animal is dead they do not always know it – all they know is that they are no longer a threat. Chimpanzees are ninety-nine percent genetically identical to humans, but overall there are obvious differences that are observable by the naked eye.
