Most primatologists believe that the enlargement and reorganization of the brain in monkeys and apes is linked to the necessity to become social animals.
<h3 /><h3>Why do primatologists believe this to be the case?</h3>
In an evolutionary sense, the ability to become social animals opens many possibilities and greatly increases the odds of survival for a species. This allows the members of a species to work together and organize tasks, expand into new territories and better adapt to all environments by working together.
Therefore, we can confirm that the enlargement and reorganization of the brain in monkeys and apes is linked to the necessity to become social animals.
