Why did humans envolve such large barins? [Sci-post1]

Human is the best ultrasocial creature on the planet.We have outcompete interbred on even killed off all other hominin species.We cohabit in cities of tens of millions of people.This is because we have an extremely large ,flexible and complex brain.

To truly understand how the brain maintains our human intellect, we would need to know about the state of all 86 billion neurons and their 100 trillion interconnection and the state of more than 1000 proteins that exit at each connection point.

We can assume our brains operates like a computer. But Robert Epstein,a psychologist at the American institute for "Behavioural Research and Technology " says this is just shobby thinking and is holding back our understanding of the human brain.As,while humans start with senses,reflexes and learning mechanisms,we are not born with any of the information, rules,algorithms on other key designed elements that allow computers to behave somewhat intelligently.

Computers store exact copies of data that persists long time periods of time,even when the power is switched off.Our brain,meanwhile, are capable of creating false data or false memories and it maintains our intellect as long as we remain alive.

We have a big brain.Thus we can take many advantages in life.But we are not computer at all,instead of that we are organisms.
The human brain is pretty programmed to be extremely flexible; it's cerebral organisation is adjustable to the society and environment in which they are raised.
So every generation can adapt to the new environment and social challenges easily.

So the next time people will turn into a computer.Just remember how big and complex your brain is --to keep a track of your friends and enemies.
