Origin and evolution of man
The stages of evolution of man are-
1. Dryopithecus and Ramapithecus-
- About 15 mya, 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 hominid features leading to the belief that about 3-4 mya, man-like primates walked in eastern Africa.
- About two mya, Australopithecines probably lived in East African grasslands.
- They hunted with stone weapons but essentially ate fruit.
- Some of the bones among the bones discovered were different.
- They were intermediate between apes and man.
3. Homo habilis-
- The brain capacities were between 650-800cc.
- They probably did not eat meat.
- They were the makers of stone tools.

4. Homo erectus-
- About 1.5 mya, Homo erectus arose.
- Homo erectus had a large brain around 900cc.
- Homo erectus probably ate meat.

5. 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.

6. Homo sapiens or modern man-
- Arose in Africa and moved across continents.
- During ice age between 75,000-10,000 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.
