I'm sure that many aspects of work and specialization are as old as humanity itself. Don't you think there was one guy in the tribe who was really good at starting fires, one woman who knew where to find the good berries, one guy who was the best at fixing spears, and some people who weren't that good at anything so they just joined the effort wherever they were needed? You don't have to have a physical exchange of currency or a 40hr desk job for that to be true.
