Brain Development And Evolution In Social Insects

How do brains evolve? If species differ in the size and structure of their brains, are there patterns to these differences? Can these patterns tell us something about the evolutionary forces that affect brain architecture? Most animal lineages sport concentrated and highly organized nervous system tissue, usually located near the front of their bodies (brains).
