New research backs a theory that insect meals helped primates — including humans — evolve better brains

You may have small bugs to thank for your big brain and its ability to creatively solve problems, say researchers working in Costa Rica. Primates are mammals such as monkeys, apes and hominids (a group that includes modern humans). Scientists had long suspected that finding and eating bugs when other food is scarce helped primates ­evolve bigger brains.
