Human Evolution factors and proofs essays

Human Evolution factors and proofs essays Human evolution is the theory that states that humans developed from primates millions of years ago. Generation by generation the genetic composition of Primates changed which eventually created humans today. There are many factors and proofs to justify this theory. The main factor was climate and the need to move locations. Fossils that were found in France were huge evidence that evolution really was how humans came to be as they are today. The main factor effecting evolution is climate. When climate changed, within time the Homo sapiens were forced to move. Because the location changed their diet was forced to change as well. Instead of only eating vegetation and nuts the Homo sapiens started eating meat. The result of eating meat forced their brain to grow from the protein, their figure started to change and they started to develop canine teeth. During the Ice Ages the Sahara desert expanded which allowed the Homo sapiens to move to Australia. While they were moving through Eastern Europe they encountered new animals. The Homo sapiens then developed better tools, such as spears, to kill off the new predators. The Homo sapiens then encountered the Neanderthals. This created a war between the two species. The Homo sapiens eventually beat out the Neanderthals and the Neanderthals became extinct. Around 10 000 years ago, once the Ice Age was over, many mammals became extinct due to the great climatic change. Humans, however, were the smartest mammals and were able to find ways to survive. Isolation was another factor of evolution. Being isolated for a long periods of time let certain traits the Homo sapiens had take over and it let certain traits die. Climate was the overall main factor of evolution and it played the biggest role. There are many proofs of Evolution. Fossils have been found that indicate that humans have not just existed but have evolved over time. Scientists have analyzed the bon ...
