The modern Homo sapiens has tripled his brain mass, so his traumatic pains!

In the last two million years in particular, there has been a dramatic increase in brain volume; it expanded almost three times! At birth, a baby with an increasingly large head, had to pass through the already narrowed birth canal. Birth became an ever greater risk for mother and child and also an evolutionary risk for the entire species.

There are basically two types of survival throughout the animal kingdom; nest-leavers and nest-sitters. Nest-sitters like humans are very problematic from the beginning, meanwhile those who leave the nest like chickens are typically very independent after a short time.

Trough Science of Body Heat, we discovered that an optimal body temperature of 37°C has to do with rapid wiring in a child's brain cells. That is, speaking, walking, laughing, it's all about the brain and body temperature of these motor activities. In another saying; less brain wiring between the cells means lower body temperature and a biological system's cell changes its strategy to fight or flight. That's the beginning of the traumatic pains....
