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 fro
Johansson discovered forty percent of a three million year old skeleton named "Lucy." He determined her to be three and a half feet tall (twelve inch femur), fifty-five pounds (wear on the hip joint), old (wisdom teeth were worn out), and one-quarter sized brain (skull casing). This find was unique because so much of the skeleton was discovered intact. Chimpanzees and humans descended from a common origin of life. We are related to one another, we did not descend from one another. Every ancestor of ours were similar to an extent, but they were all unique, which is what allowed them to dominate the Earth at one time. We know the end result of human evolution, but we do not know all of the chapters. There are too many blanks in the timeline; we need fossils to fill it in. With all these random puzzle pieces humans will never comprehend the end result completely. Human evolution is within our grasp, but we will never be able to completely grab a hold of it. 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, bu
