(1) The first hypothesis states that frugivores needed to have big brains in order to remember the locations of their foods. Primatologist Katie Milton's comparative study between frugivorus monkeys (like capuchins) and folivorous monkeys proved this hypothesis to be somehwhat correct. She found that frugivorous monkeys had to remember when and where a particular type of tree species was rippening whereas a folivorous monkey had a free range of leaves without worrying about where and when they rippened. Thus it became evident that the task frugivorous monkeys have to endure required a much larger brain. The second hypothesis suggested that some primates required a much larger brain so that they would be able to manage the complex foraging tasks they engaged in on a daily basis. Although there was insufficient information to carry out a proper scientific test of this hypothesis, it is still known that there are two genera (chimpanzees and capuchins) with conspicuously large brains as well as a heightened ability for using tools to extract food. The third hypothesis indicated that big brains enabled primates to manage their complex social lives with success. In some studies it was discovered that some primates will manipulate other monkeys to achieve a desired outcome; in fact in some observations, female capuchins would form coalitions with other females who groomed them
