  • The Big Human Brains may have been Evolution’s Way of Social Gauging

Scientists today are agreed upon the fact that the big human brains may actually have been evolution’s way of social gauging. Primitive men sized each other using the larger than usual brain which is a hallmark of our species.

The large brains of human were actually Nature’s way of allowing them to size each other up. This was done in huge social organizations.

A group of scientists have managed to find out that the daunting task of finding out more about a relative stranger based on heuristic rules of thumb was something which the human brain made possible. Its large size was reached in 2 million years of evolution. 

The study discovered that those who helped others out based on similar status and success rates tended to fare well in the scheme of things. Cooperation, not competition, ruled the roost despite what some hard core evolutionists may say.

The rise of mutual harmony and giving, loving, caring and sharing behavior evolved thanks to social comparison. This in turn was tied up with the betterment of society. What was beneficial to one person was also a boon for the rest of the members of the populace.  

The art of sizing each other up is crucial to the balance and well-being of a society. Whether we want to lend aid to someone in need depends on our social sense. It is almost like a sixth sense, this ability to gauge the level of friendliness of another member of one’s species.

Furthermore, like attracts like. Those who are similar to us, in their success rates, are more likely to be helped in their endeavors. This is only natural. Computer models were used to study hundreds of thousands of what could only be called “donation games”. Decision-making was a complex process. 

The donation strategies of two players in a game of give and take was all based on gauging the other. It took some shrewdness and horse sense. That much is for sure.

In comparison with other species such as chimpanzees, humans have a much larger brain. Our cerebral cortex is also pretty humongous when compared across the spectrum of species.

The brain areas reserved for memory, communication and cognition are well-developed. Judgments regarding others occupies much of our social life.

Whether we want to show some sympathy or empathy to others is highly dependent on lightning fast decision-making that takes a whole range of factors into consideration.

Human survival ultimately depended upon large communities cooperating for food, resources and reproduction through pair bonding. 

This study got published in the journal Scientific Reports.
