About $15\mathrm{ }\mathrm{m}\mathrm{y}\mathrm{a}$ , primates called Dryopithecus and Ramapithecus were existing. They were hairy and walked like gorillas and chimpanzees. Australopithecines probably lived in East African grasslands about $2\mathrm{ }\mathrm{m}\mathrm{y}\mathrm{a}$ . Evidence shows they hunted with stone weapons but essentially ate fruit. The first human-like being the hominid was called Homo habilis. The brain capacities were between $650-800\mathrm{c}\mathrm{c}$ . They probably did not eat meat. Fossils discovered in Java in $1891$ revealed the next stage, i.e., Homo erectus (Java Man) who lived about $1.5\mathrm{ }\mathrm{m}\mathrm{y}\mathrm{a}$ . The Neanderthal man with a brain size of $1400\mathrm{c}\mathrm{c}$ lived in near east and central Asia between $\mathrm{1,00,000}-\mathrm{40,000}$ years back.
