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
About thirty-to-forty thousand years ago, without reason or excuse, Neandertals mysteriously disappeared. They contain a large big toe in line with the others and a longitudinal arch, both characteristics of human feet. He found a skull in seventy different pieces, which he painstakingly glued together. This video went into great detail in every category of ancestors and presented us with a logical and easy understanding of all facts and theories. 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. Homo Erectus was the first "person" to hunt. It contained a broad range of information on human origin, which was interesting and exciting to watch. Chimpanzees are ninety-nine percent genetically identical to humans, but overall there are obvious differences that are observable by the naked eye. Homo Erectus was the first human ancestor to leave Africa. Human evolution is within our grasp, but we will never be able to completely grab a hold of it. Five hundred thousand years before "Lucy," a volcano erupted and three hominids walked on the ash, it rained and got sunny, drying the footprints out. Neandertals were socially organized and stronger than most. With all these random puzzle pieces humans will never comprehend the end result completely. " 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).
