To be in command of yourself is something you would like to be all the time. But it happens sometimes, for many quite often,
that you lose control of your actions.
When recently watching a documentary about evolution, some interesting data were presented, showing that it isn’t always easy to be in control of yourself.
By making a concise and probably not totally correct analysis from the perspective of a professional scientist, humans in their early phase were fishes.
Time passed, and with the ongoing evolution, the fish jumped out of the water and became a snake.
The brain of a snake is a very simple one and only reacts to vision, hunger, fear, aggression, and sexual impulses without coordination whatsoever. This uncomplicated structure of the brain we humans bring with us as evolution continues.
In the next
step in our evolution, we get characteristics of mammals, still with the “snake brain” in the background. Mammals can coordinate all different feelings and experiences. From reptiles to mammals, we became much wiser just to label the difference with something.
After millions of years, the mammals, or at least some of them, become primates, the apes most similar to today’s humans.
To get this "reptile-mammal-ape brain" to transform into a human, or what we call humans, I must add as a disclaimer, that something called neocortex is added. It’s the part of the brain just behind your forehead bone.
