Homo habilis

This is an interesting and important hominid species, which is believed to have formed the bridge between erectus and Australopithecines. However, they also lived with both these species together in different times. It has been a common agreement that these hominids were the first to evolve of the Genus: Homo. Therefore, they were believed to be the least related to modern man. However, the recent findings suggest that there was another Homo species (H. rudolfensis) fossil older than habilis. The discovered fossils of the habilis man have been named using different combinations of letters and numbers by scientists, and some of those include KNM ER 1813, OH 24, OH 07, and many more. Those fossils date back to different times, and those suggest the habilis man lived between 1.4 and 2 million years from today. Their cranial capacity ranged from 360 to 600 cm3, which is much smaller compared to the human and H.erectus. The skulls of the habilis man had a protruded structure but not as much as the chimpanzees and Australopithecines, and the face was larger than the braincase. The social structures and other activities are believed to be more sophisticated in habilis than in Australopithecines. They were skilful creatures with an advanced use of tools, but there is no evidence on the use of fire. H. habilis was only about four feet and three inches tall, and they were not robust looking.
