Primate brain size does not predict their intelligence

(Deutsches Primatenzentrum (DPZ)/German Primate Center) A research team from the German Primate Center has systematically investigated the cognitive abilities of lemurs, which have relatively small brains compared to other primates. Conducting systematic tests with identical methods revealed that cognitive abilities of lemurs hardly differ from those of monkeys and great apes. Instead, this study revealed that the relationship between brain size and cognitive abilities cannot be generalized and it provides new insights into the evolution of primates.
