How does life in the canopy shape the evolution of the mind? The foraging decisions of kinkajous - an elusive species that forages in neo-tropical forest canopies at night - may offer some clues. The central aim of this project is to identify the processes of learning and memory that allow kinkajous to keep track of when and where to find their favorite food: fruit. By comparing our findings to what is known about primates, which also live in the canopy and eat fruit, we can gain a better understanding of the general ecological factors that lead to the evolution of greater intelligence. In turn, we may be able to identify how certain habitats facilitate the emergence of complex societies by selecting for brains that are better able to learn about relationships, be they social or spatial.
