New Evidence The Genus Homo was found to be the later day modern humans which shared many of the same characteristics to homo sapiens today. The scientific specification for these mammals were homos. There were many different types of homos which all have multiple of the same qualities and characteristics. These characteristics all were classified as great apes.

Skull/ Brain Size Homo Habilis is a form of mammal that is a type of homo sapien. These human-like animals had specific skull structures and size starting out at the size of 320 ml as an infant. The skull varied over time and grew about 20-25% in their lifetime towards adulthood. By adulthood, these Homo Habilis mammals had a skull size of 400 ml which is relatively small and greater. The posterior parietal cortex of the skull was the part of the skull which was relatively large. These great apes had relatively smaller brains than the australopithecines which give the australopithecines larger brains but smaller bodies.

Tools When fossils were found of the Homo Habilis there was no evidence that was collected for these mammals that tools were constructed. Not all Homo Habilis were able to figure out how to make tools but some figured out that you need a tool to make a took and certain ones were made out of stone. Many of these stone tools were made into sharp arrow shapes to be used to kill their prey. The Homo Habilis was not the first one to discover these tool but the homo Australopithecus was responsible for the first stone tool which was called the Oldowan. The Oldowan dates back to 2.5 million years ago when they were discovered and used by these homos.
