(N/A) About $15$ million years ago $(mya)$,primates called $Dryopithecus$ and $Ramapithecus$ existed. They were hairy and walked like gorillas and chimpanzees. $Ramapithecus$ was more man-like,while $Dryopithecus$ was more ape-like.
Few fossils of man-like bones have been discovered in Ethiopia and Tanzania. These revealed hominid features,leading to the belief that about $3-4$ $mya$,man-like primates walked in eastern Africa. They were probably not taller than $4$ feet but walked upright.
About $2$ $mya$,$Australopithecines$ probably lived in East African grasslands. Evidence shows they hunted with stone weapons but essentially ate fruit.
Some of the bones discovered were different from $Australopithecines$. This creature was called the first human-like being,the hominid,and was named $Homo$ $habilis$. Their brain capacities were between $650-800$ $cc$.
