Was evolution of brain a necessity? Man being a social animal has necessary space in his skull to accommodate the wiring that would need for honing his communicative skills. Other species have comparatively not much space for what man is equipped for. Nevertheless a bee can make sense of its world as well as get the best in its brief life span. So in terms of utility a life form is never for a moment at a loss to make a go of it. If a group of lizards in Madagascar thrown into the islands with fewer possibilities of sustenance evolves into miniature version of its cousin elsewhere a biologist would say it is owing to insular dwarfism. It is so. The group has learnt to adapt itself in terms of its environment. The dynamics of jiggering with its body size, habits are as unconscious as its consequences are obvious. So brain is not merely the size and circuits but being conscious of its undeniable connection to the world outside.
Having said this let me mention about bilingualism.
If man was not conscious about other groups different from his having different languages the topic of bilingualism would be a non-starter.
Bilingualism affects the structure of the brain including both major types of brain tissue – the grey matter and the white matter. The neurons in our brain have two distinct anatomical features: their cell bodies, where all the processing of information, thinking and planning happens, and their axons, which are the main avenues that connect brain areas and transfer information between them. The cell bodies are organised around the surface of the brain – the grey matter – and all the axons converge and interconnect underneath this into the white matter.
We call it white matter because the axons are wrapped in a fatty layer, the myelin, which ensures better neuronal communication – the way information is transferred around the brain. The myelin functions as an “insulation” that prevents information “leaking” from the axon during transfer.
Brain is in fact a jumble of parts from jellyfish, lizards all put together. We are using the nerve net from jellyfishes while design features of the brain are derived from lizards. Jellyfish do not have brain and their communication system developed 600 million years ago cannot be what is best for us. The brain evolved out of necessity to take care of different groups speaking different languages do affect the structure of the brain. How is it then that some groups like the Western societies pride in their ability to explore new ideas while some resist any idea that has been associated with something sacrosanct genuine or imagined? If a non-Muslin takes the name of Allah it is tantamount to blasphemy or image of Prophet Mohammed is depicted it is an insult. What is a drawing but of the same category as letters drawn with a brush or pen or by pressing keys? If a mulla in the prophets name urges his audience to hate and kill it is not an insult to the position he holds or to his Maker?
Recalling the recent outrage of some terrorists attacking the Charlie Hebdo office in Paris makes me wonder if brain has to do with these murderers who can shoot people in the broad light in the name of their prophet. Where does their intolerance come from? Are they brainwashed to forget the consequences? Or have their brains put into sleep mode by their fear of group disapproval? If such fear can skew up their thinking brainwashing is unnecessary. Man has himself necessitated its stagnation. Religion is not detrimental to one’s onward development. It is supposed to sooth and heal divisions since moral value of any life is worth preserving.
