Xenosociology 1: Division of Labor

I've known for a while that essentially every intelligent alien species would invent money, but it only occurred to me today that they also would invent the division of labor. Because essentially every intelligent alien species will be social (for reasons I'll address in another post), they would be able to break a complex task into simpler, specialized tasks for the different members of their group. Because they would be embroiled in intraspecies conflict (ditto), the need for military advantage would drive specialization.
