Evolution of Human Species

Biodiversity today is believed to have originated from simple unicellular organisms through evolution
The origin of human evolution can be traced back to around 7 crore years ago, when dinosaurs became extinct

Early Evolution of Monkey-Like Animals

Around 7 crore years ago, monkey-like animals evolved from ancestors similar to modern lemurs
These early animals had tails, which disappeared around 4 crore years ago
As their brain size increased, their hands became more developed, leading to the evolution of ape-like animals

Evolution of Apes

Ape-like animals migrated to South and North-East Asia, where they evolved into gibbons and orang-utans
Those that remained in Africa evolved into gorillas and chimpanzees around 2.5 crore years ago
Some 2 crore year old ape species evolved differently, using their hands more for food and other activities

Emergence of Human-Like Animals

Around 2 crore years ago, ape-like animals began to live on land due to declining forests and developed an erect posture
This freed their hands for use, allowing for more complex activities
The first human-like animals with erect posture evolved around 2 crore years ago, with evidence of 'Ramapithecus' ape found in North India and East Africa

Development of Human Species

The ape-like animals continued to grow in size and intelligence, with the South African ape evolving around 40 lakh years ago
The morphology of these human-like animals began to resemble the genus Homo around 20 lakh years ago
Skilled humans developed around 20 lakh years ago, with evidence of human-like species in China and Indonesia

Development of Human Brain

The evolution of upright humans continued, with a focus on developing the brain over the next 1 lakh years
Humans discovered fire during this period
By 50,000 years ago, the human brain had developed sufficiently to be classified as Homo sapiens
The Neanderthal man is considered one of the first examples of Homo sapiens
