how did homo sapiens emerged?

The evolution of Homo sapiens involves following stages

1. Dryopithecus and Ramapithecus: These existed around 15 mya. They were hairy and walked like gorillas and chimpanzees. Ramapithecus was more man-like while Dryopithecus was more ape-like.

2. Australopithecus: Australopithecines probably lived in East African grasslands around two mya. Evidence shows they hunted with stone weapons but essentially ate fruit. This creature wascalled the first human-like being the hominid and was called Homo habilis.

3.Neanderthal man: The Neanderthal man with a brain size of 1400cc lived in near east and central Asia between 1,00,000-40,000 years back. They used hides to protect their body and buried their dead. 

4. Homo erectus: Fossils discovered in Java in 1891 revealed the next stage, i.e., Homoerectus about 1.5 mya. Homoerectus had a large brain around 900cc.Homo erectus probably ate meat

5. Homo sapiens : Homo sapiens arose in Africa and moved across continents and developed into distinct races. During ice age between 75,000-10,000 years ago modern Homo sapiens arose.
