by Randall Susman
Odyssey Adventures in Science

They are many species of early humans:Sathelanthropus tchadensis, Orrorin tugenensis, Ardipithecus, Paranthropus, Kenyapithecus platyops, Australopithecus,Homo Erectus ,Homo Habillis, Homo rudolfensis Homo georgicus, Homo  florosiensis and Homo neanderthalensis.The Sathelanthropus tchadensis were discovered for the first time in Africa, they are beetween 6 and 7 million years old. Their brain was really small compared to ours and they are still debats on their ability to walk. Still found in Africa, the Orrorin tugenensis is  between 5.8 and 6.1 million years old. By looking at the position of the skull we also know that they were bipeds that were able to climb trees.  The Ardipithecus were found in Ethiopia and were about 4.4 million years old.We don't know a lot about them. The paranthropus were about 2 million years old, they were first found in Kenya. They were mostly vegetarians and were bipedal. The Kenyapithecus platyops were also found in Kenya and lived about 3.5 million years ago., it is all we know about them.  Australopithecus lived during about 2 million years between 4 million years ago to 2 million years ago. According to Randall Susman, "Two species of this group Australopithecus anamesis and Australopithecus afarensis are the most ancient.Athird species Australopithecus africanus is more recent". They were discovered in Chad and were bipeds. Homo Erectus were 1.8 million years old and were technically more advanced. Homo habilis were bipedal that could make and use tools, they had bigger brains and ate meet.Homo rudolfensis, as all the other homo lived about 2 million years ago. Homo georgicus lived around 1.8 million years ago," they are closse H.Habilis in brain Size". Homo florosiensis were dated 18000 years old but had physical features of a homo. Homo neanderthalensis are the closest to humans, they live between 250000 and 30000 years ago.
