Darwin's DNA

"You can't handle the truth", so instead you lie. I couldn't count the times that I have lied because truthfully I have lost count. We lie about almost everything and sometimes for absolutely no reason. But why do we do this?

The book "Darwin's DNA" suggest that we lie in order to survive. That our brain lies to us. That our brains manipulate our perceptions of the world in a manner that would mostly likely cause us to survive. One of the examples used in the book is that of the blind spot where the optic nerves attaches to the eye, the brain constructs an image that we would believe belongs there based upon the surrounds we are in. The brain basically makes up a part of the world we think are seeing, I think it does this because we like to perceive the world or what we are looking at as a whole not with a hole. Our brain create scenarios that are very unlikely because it could help us survive. As children our imaginations where rather active, and we would create monsters under the bed and in the closet that we would think eat us, so we always checked before we went to bed. As adults we monitor the areas around the house, setup light and security systems to avert predators. The habit of checking areas where things or people can hide helps us by making us aware of our surroundings, making sure we are safe from the imaginary monsters and the real predators of humans and animals.
