Answer» - Human evolution states that humans developed from primate or ape like ancestors.
- Human origin occurred in Central Asia and Africa, China, Java and India (Shivalik hills).
- The first mammals were shrew like terrestrial, insectivores or rat like creatures.
- The insectivorous mammals namely tree shrews gave rise to the primitive primates called prosomians which include tarsiers, lemurs and lories and anthropoids (marmosets, baboons, monkeys, apes and man).
- Modem man Homo sapiens belongs to class mammalia, order primata and suborder anthropoidea.
- Dryopithecus africanus is regarded as common ancestor of man and apes.
- It is lived about 20 – 25 million years ago (Miocene).
- Dryopithecus gave rise to Rama pithecus; he appeared 14- 15 million years ago.
- The fossil of Rama pithecus was discovered from Pliocene rocks of Shivalik hills of India by Edward Lewis.
- Rama pithecus gave rise to Australo pithecus after a gap of 9 – 10 million years.
- Rama pithecus the first ape man commonly called southern ape .He appeared about 5 million years ago (early Pleistocene).
- Homo habillus lived in early Pleistocene about 2 million years ago.
- He was the first tool maker or handy man.
- Homo erectus is the direct ancestor of modern man.
- Homo erectus evolved from homo habillus about 1-7 million years ago in middle Pleistocene.
- Homo erectus include Java ape man, pieking man and Heidelberg man.
- The Neanderthal man existed in the late Pleistocene he was roughly equal to the modem man.
- Cro-Magnon is regarded as direct and most recent ancestor of the living modem man.
- He lived about 34.0000 years ago in Holocene epoch.
- The cranial capacity was about 1650cc and considered more intelligent than the man of today.
- The modern man Homo sapiens arose in Africa about 25.0000 years ago in Holocene epoch.
- It is believed that the man of today appeared about 11.000 or 10.000 years ago in the region around Caspian and Mediterranean seas from their members migrated west wards, eastwards and south wards respectively changing into present day white or Caucasoid, Monogoloid and black or Negroid races.
- Modern man underwent cultural evolution. Cave art developed about 18.000 years ago.
- Agriculture came around 10.000 years back and human settlement started.
