       ** Have you ever thought about how you got here? Have you ever heard someone say that humans came from monkeys or apes? Well that isn’t exactly true. The theory was that humans and monkeys are common ancestors. Scientist has found enough evidence to support this theory. Many fossils and skeletons have been found that show relations of monkeys and humans. http://www.african-safari-pictures.com/image-files/baby-chimpanzee-picture.jpg What exactly makes us humans? What are we classified as? Humans are classified as primates. Primates are a group of mammals that includes humans, apes, monkeys, and lemurs. Primates have charcateristics such as binocular vision, and opposable thumbs. Binocular vision is when both eyes are located at the front of the head, and they provide three-dimensional cision. Opposable thumbs menas that primates have five flexible fingers, and an opposable thumb. http://www.amnh.org/exhibitions/permanent/humanorigins/past/images/md/113b_hands.jpg Scientist believes that the chimpanzee, which is a type of ape, is the closest living relative to humans. This doesn’t mean that we came from chimpanzees; it means that we are common ancestors. Sometime between 6-30 million years ago humans ancestors (chimpanzee), and other apes began to evolve. ** ** Humans are in a special group not related to primates. This special group is called Hominids. Hominids is a type of primate that has different traits by bipedalism. Bipedalism is a really BIG word. It means “walking straight, and on 2 feet.” Evidence of this can be found in a primates body structure. The earliest hominid had traits that were human-like opposed to being ape-like. For example, these traits included smaller teeth, flatter faces, larger brains, and the ability to walk upright or straight. Primates had bigger teeth, bigger faces, larger brains, and the non-ability to walk upright. ** ** The oldest hominid fossils were found in Africa. So, scientists think hominid evolution began in Africa. Many early hominids are classified as //australpithicines//. Members of this group were similar to apes but were different in many different ways, For example, their brains were slightly larger than the brains of apes. Some of them may have used stone tools. They also climbed trees but could also walk on two legs. Fossil evidence of australopithecines has been found in several places in Africa. Many australopithicines, and other types of hominids lived in the same time frame. About 2.4 million years ago a new groups of hominids began to walk the planet. These hominids were very similar yo australopithecines, but were more humanlike. This new group of hominids had bigger, and more complex brains, rounder skulls, and flatter faces than the earlier version of hominids. This new group showed advanced-tool making, and could walk upright. This new group became members of the group //homo//, which included modern-day humans. An early member of this //homo// group called //homo habilis//, which lived about 2.4 million years ago. Then about 1.8 million years ago a new homo appeared called //homo erectus.// These hominids could grow as tall as a modern day human. Scientists couldn't really figure out what these new hominids looked like but they have made guesses as to what they looked like. [[[]  **                   **As early as 30,000 years ago, two types of hominids may have lived in the same areas at the same time. Both**    **  having the biggest brains of all hominids. Scientists have come up with a theory, believing that humans may have descended form from one of these two types of hominids. One of the most recent hominids were the //Neanderthals//. Neanderthals lived in Europe, and certain parts of Asia. They might have lived as early as 230,000 years ago. Neanderthals liked hunting large animals, made fires, and wore clothes. Neanderthals eventually became extinct 30,000 years ago. Scientists do not know the cause of their disappearence.

The earliest homo sapien lived in Africa about 100,000 to 160,000 years ago. The group migrated out of Africa sometime between 40,000 to 100,000 years ago. Homo Sapiens had smaller, and flatter faces. they also had a smaller skull compared to Neanderthals **.

Almost all pirmates have oppasablt thumbs, and binocular vision. Hominids which are a subgroup of the primate family, include humans, and their humanlike ancestors. The oldest hominid may have lived 7 million years ago. The earliest hominids included australopithecines, and the //homo// group. Early //homo// sapiens did not have many defferneces from modern-day humans. //Homo// sapiens are the only living hominid today.
