I think biologically we evolve to be polymaths. Only after humans formed complex societies we have opportunities that sustainably reward specialization. And there is probably very little genetic reinforcement of modern specialization. Don't have my own experience but from what I see, family life of a polymath seems much more rewarding and with a lot of genetic reinforcement. The Revenant might be a good example of 2 stages of evolving human societies where one totally rewards Polymaths and in other you probably want to start being a specialist.
