BRAIN PART 2

In my previous blog, I gave a glimpse about the complexity of the brain. In todays blog, I am going to shed some light on the history of human brain. Now what I mean by history is about the evolution of brain from an insignificant mass of cell to become the most powerful piece of machinery nature had ever created. So without any further due lets hop into it.

The first living cell emerged on earth atleast 3.8 billion years ago, approximately 750 million years after the earth was formed. Its hard to wrap our head around these gigantic numbers and there is a reason behind it. And the reason is human mind cannot comprehend these large numbers because in day to day life we do not encounter numbers on the scale of billions or millions. Mind of Homo Sapiens was not forged to encapsulate these huge numbers. Then after the emergence of the first cell, life began to flourish to different parts of the world. Single cell organisms like bacteria, protozoa started to emerge. Slowly with the passage of space and time, cells began to clump up and started coordinating with each other, making connections and started working as a unit. And thus multicellular organism emerged from this act. And among these cells, some of them began to conduct and generate electric impulses. These cells are later termed as NEURON. The previous sentences might have ended in few words, took me few seconds to type it down but believe me it took millions of years for this event to occur. Evolution is a slow and steady process with no direction.

Our brain is simply a collection or a group of billions of neurons forming trillions of patterns and combinations. Its the firing of neuronal pathways that defines who we are. It governs our day to day activity and without the aid of brain or a mind humans have no identity. Individualism will come to an end without it. That’s why in medical world, doctors declare a person dead when his/her brain is dead. It is called CLINICAL DEATH.

“Homo Sapiens rule the world because it is the only animal that can believe in things that exists purely in its own imagination such as God, states, money and human rights” by YUVAL NOAH HARARI

I believe there is something different about the human brain that seperates us from every organism on earth. In recent times, scientists are trying to resurrect our closest anchestor “THE NEANDERTHALS”. What they will try to do is compare our brain with that of the neanderthals to spot the difference between the two. By doing so scientists believe that they will get a clue about the orign of CONSCIOUSNESS. What changes might had happened in our brain that made us conscious. This resurrection act has both ethical and scientific implication and purpose. It is ethical because due to the emerge of Homo Sapiens, the less superior Neanderthals got extinct, so it is our moral duty to resurrect them. The big question is Why only the chimps, not any other organism nature had choosen to boon with consciousness? What is actually special about the red butt, tree climber born with the face of Mythical God Pawanputra Hanuman ? These questions are yet to get answered.

The Foundational dogma of life on earth is : ORIGN -> GOT COMPLEX -> BECAME INTELLIGENT.
