Scientists had Long thought that Stone tools dated around 2.4 million to 2.6 million years old were made by a member of the evolutionary group Homo but they did no to have evidence. The oldest fossils firmly attributed to Homo were about 1.9 million years old. A now Homo is available to have made the first known Stone tools a said study co author Andrew Hill. The tools were found in Ethiopia. Hill a Yale University anthropologist reports the analysis in thursdays Issue of the journal nature. Also contributing to the research were Steven Ward of the northeastern Ohio universities College of Medicine in Rootstown and Alan Deino and colleagues at the geochronology Center of the Institute of human origins in Berkeley Calif. They studied a Fossil unearthed about 25 years ago in Kenya a 3-Inch Bone fragment that included the Hole for the right ear and the part that met the lower jaw. When the find was reported researchers said they did not know whether it came from Homo or from related creatures called . The Homo evolutionary group includes the extinct Homo Kabilis and Homo Erec Tus As Well As people called Homo Sapiens. The new analysis used comparisons to skulls from Homo and  that had been discovered since the Fossil was unearthed Hill said in a Telephone interview. Researchers cited two features characteristic of Homo. One indicated that part of the creatures brain was directly Over the jaw joint whereas in  the brain did not extend out that far. The other characteristic was the Sharp Angle of a Ridge of Bone called the Petrous Crest on the inside of the Skull. The Fossil had too Little information to be assigned to a particular member of Homo Hill said. The age of 2.4 million years was determined from analysing rocks from the site where the Fossil was found. Bernard Wood of the University of Liverpool who wrote a nature editorial on the study said that he believed the Fossil was Homo but that the conclusion must be considered tentative. Wood said other Fossil remains had previously been proposed As coming from Homo at dates older than 2 million years but that the supporting evidence was ambiguous. Hill said the new finding lends support to a hypothesis that a global Cooling about 2.4 million years ago played role in the appearance of Homo.
