For a long time, science could not explain why our brains grew so much in size and became disproportionately large in relation to our bodies. In the past, evolutionists believed that complex thought processes were at the core of human carnivorous habits and the need for social interaction. According to recent studies, for our huge brain, we should thank the need to constantly think and ... run.
To reach this conclusion, anthropologists used animal examples - from guinea pigs to wolves to sheep - to study the relationship between brain size and endurance. They noticed that the species that nature has bestowed with better endurance, the brain was larger in relation to body size.
The researchers studied mice and rats that were purposefully bred to compete in marathons. They created laboratory animals that excelled at running and crossed them with those that performed best on the squirrel wheel. In newly hatched animals, the level of concentration of the neurotrophic factor of the brain, which stimulates the growth of healthy tissue, began to increase.
The moral is this: exercise is necessary in order to be even smarter, stronger and more educated.
