Write evolutionary history of modern man.

Explanation

Human evolution began approximately 7 crore years ago.
The sequence of evolutionary history of modern man is as follows:
i. The last dinosaurs disappeared 7 crore years ago.
ii. Monkey -like animals are said to have evolved from ancestors that were similar to modern lemurs aroung the same time.
iii. Ape-like animals (Aegyptopithecus) evolved aroung 4 crore years ago, by the disappearance of tails, enlargemen of brain and improvement in the functioning of hands.
iv. In Africa these ape like animals evolved into gorillas and chimpanzees around 2.5 crore years ago (Dryopithecus)
v. Human like animals who used their hands for eating hand other work evolved around 2 crore years ago.
vi. These animals lived on land, as the forests declined due to dry environments.
vi. Their lumbar bones developed enabling them to stand in an erect posture in grasslands, thus leaving their hands free for use.
viii. The first record of this human like ape in East Africa, was Ramapithecus (around 1 crore years ago).
ix. Around 40 lakh years ago, these apes grew larger in size and became more intelligent (Australiopithecus).
x. Around 20 lakh years ago human-like animals shared morphological similarities wiht the members of genus Homo, and thus skilled human developed.
xi. Around 15 lakh years ago human walking with an erect posture evolved and may have existed in China, Indonesia and the Asian subcontinent.
xii. Neanderthal man evolved around 1.5 lakh years ago.
xiii. For around 1 lakh years from then, man evolved by developing his brain (improving their cranial capacity) and also discovered fire during this period.
xiv. The brain of 50,ooo year old man evolved in such a way that it could be considered as member of class-wise man (Homo sapiens)
xv. Cro-Magnon man evolved around 50,000 years ago after which evolution became more faster.
xvi. 10,000 years ago present day modern man started practising agriculture, rearing cattle and establishing cities. Also, cultural development took place around this time period.
