Human Evulation :
The biodiversity that is known today has been said to be formed from very simple unicellular organism due to evolution. In this evolution, origin of human evolution can be shown as per the picture given below. Last dinosaurs disappeared approximately seven crore years ago. At that time, monkey-like animals are said to be evolved from some ancestors who were more or less similar to the modern lemurs.
Tail of these monkey-like animals of Africa is said to be disappeared about 4 crore years ago. They developed due to
enlargement in brain their hands were also improved and thus ape-like animals were evolved. Meanwhile, these ape-like animals reached the South and North-East Asia and finally evolved into gibbon and orangutan.

Those apes started to live on land as the forests started to decline due to dry environment.
Their lumbar bones developed in such a way that they started to stand in erect posture in
grasslands and thereby their hands became available for use, anytime.
These first human-
-like animals with erect posture which were using their hands have evolved about 2 crore
years ago.
First record of human-like animal is with us in the form of ‘Ramapithecus’ ape from
East Africa.
Afterwards, this ape grown up in size and became more intelligent and thus the
ape of South Africa evolved about 40 lakh years ago.
Neanderthal Human Intelligent:
The morphology of these
human-like animals started to
appear like to be the member of
the genus Homo, about 20 lakh
years ago and thus skilled human
developed.
About 15 lakh years
ago, human walking with erect
posture was evolved. It may have
existed in China and Indonesia of
Asian continent.
Evolution of upright man continued in the direction of developing its brain for the period of about 1 lakh years and meanwhile it discovered the fire. Brain of 50 thousand year old man had been sufficiently evolved to
the extent that it could be considered as member of the class- wise-man (Homo sapiens).
Neanderthal man can be considered as the first
example of wise-man. The Cro-Magnon man evolved about 50 thousand years ago and afterwards, this evolution had been faster than the earlierAbout 10 thousand years ago, wise-man started to practice the agriculture.
It started to rear the cattle-herds and established the cities. Cultural development took place.
Art of
writing was invented about 5000 years ago and thus the history had been started. Modern
sciences emerged about 400 years ago and industrial society was established about 200
years ago and now we have reached at this stage, and still we are searching the details of
roots of human ancestry.
