Evolution of Man


This question keeps on intriguing me that who was first man?

I always ask myself that there had been Adam before Adam or not.How man evolved?how man originated?I tried to find the answers by doing little research.

Human evolution started from primates.Various divergences among apes,gibbon and orangutans occurred in Homini.

It is believed that first ever human emerged in Africa around 2 million years ago long before Homo Sapian appeared on earth.

Homo Hibalis 

Homo hibilis is known as handy man.They live between 1.33 to 2.4 million years ago in Africa.They were least similar to modern humans as they had long arms and large brain.Homo hibilis is considered to be ancestors of homo erectus.They invented stone tools and these were more advanced tools than previous primates.It gave them an edge to cope with hostile environment. Their food was plants nuts and tissues of animals but studies suggest that they had very high mortality rate so all disappeared. 

Homo Erectus 

Homo is a Latin word meaning human and erectus indicates species's ability to walk and stand.

Age

Homo Erectus  were found between 100,000 and 1.6million years ago in Africa.But they dispersed toAfrica, Europe ,South Asia and South East Asia.

Physical description 

This species had robust structure like modern man.The skull of homo erectus was different. They  had double the size of brain but body was short.They had long face with less dominant chin.They were carnivores and cave dwellers.

Life Style

They discovered stone tools about 1million years ago in China.They flakes and choppers and were big in size.With the passage of time they got shorter and this specie learnt how to control fire.These stone tools were found in East Asia rather West Asia,Africa and Europe.

Neanderthal

They came in being around 200,000 years ago and were replaced by modern man between 35000 to 24000 years ago.

Modern human who spread in Asia interbed with Neanderthal.They were the ancestors of all human outside Africa.Interbreeding had enabled modern man to adapt new environment.Some of DNA of Neanderthals is found in Homo Sapiens which has its pros and cons as well .

Neanderthal Charactertics

They lived in limestone caves.They preserved bones.They were archaic humans.They were genetically and behaviourally different from living human.They developed cultue of their own.They used stone tools for hunting.They survived before and during last ice age and their survival is greatest example of human adaptation.They had long legs,muscles and good posture.

Homo Sapiens

The oldest fossils of homosapien have been found in Morocco dating back to 300,000 years.The skull size is same but brain case is very elongated.

Some researches suggest that modern humans originated in Africa 200,000 years ago and evolved.But its still debatable issue.

Well homosapien means wise man. Early human who migrated out of Africa were not successful.They had severely cold weather due the volcanic eruption in sumarta 70,000 years ago almost all of them disappeard.Some of them who were able to survive through cooperation may have led the foundation of close family groups.

Another wave of human moved from Africa between 80,000 and 50,000 years ago.They were modern humans in their behaviour. They were successful at survival and quickly spread in a whole world. Today's modern population of 6 billion is Homo Sapien which ventured out of Africa. 

This is all I conceived but its not yet final conclusion because research on our origin is on and investigating more.

Comments

  1. Charles Darwin did phenomenal research on evolution not just of man.but every form.of life. His book The Origin of Species is a monumental work. Further research by anthropologists has revealed more details about human species.
    But we donot know where we are headed. Thevway we are destroying our environment we may ourselves become extinct eventually
