Free Essays on Primate Evolution

Human evolution, the biological and cultural development of the species Homo Sapiens, or human beings. A large number of fossil bones and teeth have been found at various places throughout Africa, Europe, and Asia. It gives idea of human evolution during past 4 million to 5 million years. From a genome view point, the difference between modern man and the modern apes is only about 2 percent. From a physical viewpoint the greatest difference is in locomotion. The human walks upright, it is generally thought that this came about when the ancient hominid adopted the edge of the forest and plain and adapted to a life under the trees as opposed to in them. Fossil evidence shows that is bipedal adaptation was completed quite early, perhaps as early as four million years ago, long before we do today. Facial feature changes toward the modern appearance came much later. The facial characteristics, of modern man are about 100,000 years old. The faces of earlier hominid were much more apelike. Any mutation must be applied to a DNA coding that already exists. It can not be applied to coding that does not exist. is this a silly statement? No at all. It leads to the way that evolution changes an organism. Mutations a real ways applied to the existing DNA coding. Evolution makes something new out of something that already exists. If a bear becomes distressed in a given environment, it does not sprout wings and fly. Instead, such things as longer legs or claws will be tested. Also, evolution often does not fix the thing that causes a problem, it patches the problem by doing something unrelated. If an organism suffers a mutation that shortens its life so that it has difficulty rearing its children to childbearing age, that mutation will started being culled from the gene pool. Before that mutaion has been completely removed from the gene pool, another mutation may occur which shortens, the ge! station per...
