Bowel “decides” not worse brain
When it comes to life and death, you can’t attempt to rationally comprehend the situation, and to trust what you “gut feels”.
In his article, published in the journal Proceedings of the Royal Society B, researchers from Exeter University (UK) write that in order to survive in difficult and dangerous circumstances, all animals, including humans, do not need to be “seven spans in a forehead”. Instead of every time to use the intellect that requires energy resources, enough to listen to the signals sent by the body, primarily the intestines. The feeling of hunger can give great advice regarding behavior in a given emergency situation and it is such a simple adaptive survival mechanism supported by natural selection.
Scientists have built a computer model of animal behavior in conditions where access to power sources is not predictable and the environment is teeming with predators. The model showed that animals who base their decisions solely on their available energy reserves to survive not worse than those who enables the brain to calculate the best strategy.

“The model allows to explain the existence of the relationship between our “gut” and take us solutions: hunger works as a form of memory which says that we are in a situation of shortage of food. In the wild, such information is extremely important. The body reminds of past successes and shows how to behave in the future. This simple physiological memory allows animals to avoid investment in the development of brain tissues that require large energy costs,” explained the study’s lead author Andrew Higginson (Andrew Higginson).
