The Brain Evolution

The emergence of human race whiz ontogeny net be chased back to the Carboniferous Period 365 jillion geezerhood ago. Our brain first consisted of the most primitive part, hypothalamus only. Then it had evolved to assemble another limbic system around 200 million years ago and finally reached its final typify of evolution, the brain cortex around 2.58 million years to 12,000 million years ago. Our human brain size of it has increased multiple since the age of Australopithecus. There are many possible theories and hypothesises which can explain this enlargement of brain size. Among the theories, the most powerful tenability or factor that caused such a dramatic evolution of human brain is the well-disposed brain hypothesis.

There is a truism that the real challenge in human milieu throughout history affected the evolution of the intellect was the requirement to deal with one another in social circumstances. well-disposed circumstances stands for interactions between one another. Evidence has shown that the neopallium symmetry has a positive correlation with the mean group size, suggesting the neocortex ratio of the people in the bigger clique size is higher that that of smaller clique size. There is also a statistic showing the cranium capacity is 0.79 correlated to the population density.



The brain was believed to evolve as the same time with the human language. eer since language and speeches are developed to enhance social interactions, our human brain is further developed. As interactions were more frequent as soon as language or even brand languages were emerged, there were even higher frequency in social interactions within a clique. These interactions includes grooming others, males strategies to close in female, social play, tactical deception, etc…

There is also research showing the larger than brain is, the more intellect one is. Or more of less related to ones IQ. From this saying and the social brain theory combined together, people who is from a denser population would be smarter...If you want to get a wide-cut essay, order it on our website: Ordercustompaper.com
