Origin And Stages of evolution of man on earth

About 15 million years ago, primates called Dryopithecus and Ramapithecus were existing.
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 human features leading to the belife that about 3-4 mya,
man-like primates walked in eastern Africa. They were probably not taller than 4 feet but walked up right.
Tow mya, Australopithecines probably lived in East African grasslands. Evidence show they hunted with stone
weapons but essentially ate fruit. Some of the bones among the bones discovered were different. This creature was called the first human-like being the hominid and was called Homo habilis. The brain capacities were between 650-800cc.
They probably did not eat meat. Fossils discovered in Java in 1891 revealed the next stage, i.e., Homoerectus about 1.5
mya. Homo erectus had a large brain around 900cc. Homo erectus probably ate meat.

                The Neanderthal man 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.  During ice age between 75000-10,000 years ago modern Homo sapiens arose.  Pre-historic cave art developed about 18,000 years ago.  Agriculture came around 10,000

years back and human settlements started. The rest of what happened is part of human history of growth and decline
of civilisation.
