 * __// The History of Human Evolution //__**

 **         Have you ever heard someone say that humans descended from monkeys or apes? Well, scientists would not exactly say that. The scientific theory is that human, apes, and monkeys share a common ancestor. A common ancestor means the organism or being a species evolved from. This common ancestor probably lived more than 45 million years ago.     Many fossils of organisms have been found that show traits of both humans and apes. Also, comparisons of modern humans and apes support the theory of a common ancestor      .    <span style="COLOR: #00ff69; FONT-FAMILY: Arial, Helvetica, sans-serif"><span style="FONT-FAMILY: 'Arial Black', Gadget, sans-serif"> <span style="FONT-FAMILY: 'Arial Black', Gadget, sans-serif">Primates are a group of mammals that includes humans, apes, monkeys, and lemurs. For p rimates both eyes are located at the front of the head and they provide binocular, or three dimensional, vision. Also almost all primates, such as orangutans, have five flexible fingers-four fingers and an opposable thumb. This thumb enables primates to grip objects. Most primates besides humans also have opposable big toes. ** http://upload.wikimedia.org/wikipedia/commons/f/f6/Thumbs_up.JPG

Betweem s ix million and 30 million years ago the ancestor of human’s chimpanzees, and other apes began to evolve along different lines. http://whatwouldchimpdo.org/images/announce/chimpanzee.jpg <span style="FONT-SIZE: 160%; COLOR: #000000; FONT-FAMILY: 'Arial Black', Gadget, sans-serif"> http://store.drumbum.com/media/chimpanzee-bass-player.jpg

Humans are in a family separate from other primates. This family, called hominids, and it includes only humans and their human like ancestors. The main characteristic that separates hominids from other primates is walking upright on two feet. Scientists calls this bipedalism. http://www.dkimages.com/discover/previews/874/35020554.JPG

<span style="FONT-SIZE: 160%; COLOR: #000000; FONT-FAMILY: 'Arial Black', Gadget, sans-serif">Hominid: hominid is a type of primate characterized by bipedalism, relatively long lower limbs, and lack of a tail. <span style="FONT-SIZE: 130%; FONT-FAMILY: 'Arial Black', Gadget, sans-serif"> <span style="FONT-SIZE: 130%; FONT-FAMILY: 'Arial Black', Gadget, sans-serif">Scientists have found 18 different types of hominids. Each type is unique in terms of size, the way it walked, the shape of its skull, and other characteristics. <span style="FONT-SIZE: 130%; FONT-FAMILY: 'Arial Black', Gadget, sans-serif"> The earliest hominids had traits like the ability to walk upright, smaller teeth, flatter faces, and larger brains earlier primates. The oldest hominid fossils have been found in Africa, so scientists believe hominid evolution began there about 6 to 7 million years ago. <span style="FONT-SIZE: 130%; FONT-FAMILY: 'Arial Black', Gadget, sans-serif">Many early hominids are classified as australopithecines, which had brains that were slightly larger than the brains of apes. Some may have used stone tools, and climbed trees. They walked on two legs. Some australopithecines had slender bodies, small, apelike skulls and humanlike jaws and teeth. Some scientists think they may have been ancestors of modern humans; others disagree. http://img.tfd.com/wn/2D/61BA8-australopithecus.gif //Australopithecus// <span style="FONT-SIZE: 160%; COLOR: #000000; FONT-FAMILY: 'Arial Black', Gadget, sans-serif"><span style="FONT-SIZE: 120%; FONT-FAMILY: 'Arial Black', Gadget, sans-serif"> <span style="FONT-FAMILY: 'Arial Black', Gadget, sans-serif">About 2.4 million years ago, a new group of hominids appeared that were similar to the slender australopithecines, but were more humanlike. They were members of the group called homo. <span style="FONT-SIZE: 120%; FONT-FAMILY: 'Arial Black', Gadget, sans-serif">An early member of this group was called homo habilis, which lived about 2.4 million years ago. About 1.8 million years ago, a hominid called homo erectus appeared. http://i.cnn.net/cnn/2004/TECH/science/02/12/coolsc.thickskulls/vert.homo.erectus1.jpg

<span style="FONT-FAMILY: 'Arial Black', Gadget, sans-serif">Scientists believe that humans may have descended from one of two types of hominids, Neanderthals and Homo sapiens, both of which still existed about 30,000 years ago. <span style="FONT-SIZE: 110%; FONT-FAMILY: 'Arial Black', Gadget, sans-serif"><span style="FONT-FAMILY: 'Arial Black', Gadget, sans-serif"><span style="FONT-SIZE: 130%; FONT-FAMILY: 'Arial Black', Gadget, sans-serif"> <span style="FONT-FAMILY: 'Arial Black', Gadget, sans-serif"><span style="FONT-SIZE: 110%; FONT-FAMILY: 'Arial Black', Gadget, sans-serif"><span style="FONT-SIZE: 110%; FONT-FAMILY: 'Arial Black', Gadget, sans-serif"><span style="FONT-SIZE: 90%; FONT-FAMILY: 'Arial Black', Gadget, sans-serif"> Neanderthals lived in Europe and western Asia. They hunted large animals, made fires and wore clothing. They also may have cared for the sick and elderly and buried their dead with cultural rituals. http://images.google.com/imgres?imgurl=http://www.gonzalobarr.com/blog/wp-content/uploads/2008/04/dumb-neanderthal.jpg&imgrefurl=http://www.gonzalobarr.com/blog/%3Fp% Homo sapiens lived in Africa some 100,000 to 160,000 years ago. Homo sapiens had a smaller and flatter face, and had a skull that was more rounded. Homo sapiens created large amounts of art. The preserved villages and burial grounds of early humans show that they had an organized and complex society. <span style="FONT-FAMILY: 'Arial Black', Gadget, sans-serif"><span style="FONT-SIZE: 150%; FONT-FAMILY: 'Arial Black', Gadget, sans-serif"><span style="FONT-FAMILY: 'Arial Black', Gadget, sans-serif"><span style="FONT-SIZE: 130%; FONT-FAMILY: 'Arial Black', Gadget, sans-serif">
