Army ant (Eciton) soldiers are bigger but do not have larger brains than other workers within the same colony that fulfill more complex tasks, according to a new study. A collaborative team of researchers suggests that because the very specific and limited tasks soldiers fulfill place limited cognitive demands on them, investment in the development of brain tissue is also limited.
