What evidence shows the changing from the early hominids to the modern humans? Throughout the human evolution body parts like legs and harms have changed for the better. By the early hominids being biped, meaning they are able to stand and even walk on two feet, it helped them to be able to do more things like getting around more and help with their tool making and hunting. A lot of the fossils discovered were found in the Great Rift Valley in East Africa, which contained many different lakes and small rivers. For many years researchers have been finding new species. These species have been named Australopithicus, robust australopithecines , Orrorin tugenensis, Homo habilis, Homo erectus, neanderthal, and Homo sapiens. These early hominids and modern humans really show off how the features and behaviors have really changed in time.
Austalopithicus meaning “southern ape” was the first specimen to be found. The Austalopithicus was found in African and was know to have lived from 4.2 to around 1.0 million years ago (Standford 251). They had a small body like an ape that would get approximately 64 to around 100 pounds. They had a big jaw with a U-shaped mouth of small teeth. The brain size of a Australopithicus was small and would get approximately 340 to 500 cc, which is in the same range as gorillas and chimpanzees brain sizes. The top of their skull was of a bony ridge. They were able to walk on their two feet and had a small pelvis. The Australopithecus were found with stone tools, which made them the first stone tool makers.
Orrorin tugenensis is known to be the second oldest hominin ancestor annd possibly related to modern humans. It was also known as the “Millennium Man” because the Orrorin tugenensis was fou...

...d was made of thick bones and had a low cranial vault. Their face also consist of a big arching browridges just above their eyes (Stanford 302).
Throughout the human evolution fossils have been found and each bone discovered demonstrates how the early hominids to the modern human features have changed. Each bone showed off different stories and new facts. Even the inner ear bone has changed in shape and in size throughout the early hominids. Over time the littlest things have changed but it seem like it helped surviving better, by helping to be able to be bipeds and tool making. The early hominids are truly amazing and indeed have been an important part of modern humans and the human evolution its self.

Human ideologies of how the evolution of man came to be is determined by cultural beliefs that have been adopted by societies going back as far as the Upper Paleolithic era, some 40,000 years ago.
