What is evolution but adapting things that are already existing? Thus we have some primitive parts from lizards and jellyfish.As a result our brain at its best have to account for what it is built upon.
“Although the things it can do are very wonderful and impressive, its design is very poor engineering in many respects,” says David Linden, a professor of neuroscience at Johns Hopkins University in Baltimore, the author of The Accidental Mind.
These parts may have been OK for their original owners, he says, but they aren’t ideal for us.
Take brain cells, for example.
“They are slow. They are inefficient. They leak signals to their neighbors,”
We’re still using a communication system developed 600 million years ago by jellyfish.
Deep Down, We’re Lizards.
Jellyfish don’t have a brain, but they were the first animal to have any sort of nervous system. It’s a loose network of nerves called a “nerve net,” says Chet Sherwood, who studies brain evolution at The George Washington University in Washington, D.C.
Evolution’s tinkering gave lizards the brain they needed to hunt and survive in a tough world, and our brains still have that ancient wiring.
The brain of an adult human is about three times the size of a gorilla brain.
In evolutionary terms big brain gave our human ancestors bigger volume for brain and it is still evolving and at the root of it we still have the reptilian brain.
Brain has two halves like walnut. These are shot through two worlds: conscious and unconscious mind. our conscious self does not initiate all behaviours. Instead, it is somehow alerted to behaviours that the rest of the brain and body are already planning and performing. Also keep in mind conscious experience does play some moderating role. We think rationally and we speak as though we understand what we speak about. But do we?
Take the matter of religion.
Religion relies on mystery and requires certain rituals and symbols to maintain this mystery. People are ready to defend their faith to death. On the other hand what about the fascination with iPad or iPhone for which people are ready to kill themselves? Or do desperate things disproportionate to the intrinsic value of objects themselves, and sell their kidneys as one did in China only last week? People queue through the night, despite the inclement weather to be the first to grab when shops are opened for business. Are we not seeing Progress masquerading religion in this case? Some Nerd who cannot do anything else makes a jargon and creates applications into program and lo and behold, he is looked upon with wonder. He is a modern shaman. Craze for latest gadgets is controlled by which part of our being? Unconscious mind or Rational mind?
Our brain evolved over some 6 millennia as I mentioned earlier is not the best,- and communication system leaks, and we have no idea which part of it is triggering us?
Brain is our thinking part but it depends how we want to interpret external impressions that we see.
In an earlier post I wrote about Cosmic Mind. We make our experience as basis and draw necessary conclusions from these events around us. If we are thinking from our unconscious mind a little and from conscious mind we cannot tell.
When we look into brain we are going down in time,
