Compare: -- She bought the car from the man who was a friend of her brother. -- She bought the car from the man. He was a friend of her brother. In fact, because of the processing complexity of relative causes, paratactic constructions may take less effort. Rethinking what Alex Fink had said, and given the number and diversity of natlangs in the world, it wouldn't surprise me if there was one which did not allow the conjoining of some part of speech. If that is the case, though, I would suspect that under normal diachronic evolution, some word, a comitative for example, would be pushed into service to function as a conjunction for that part of speech.
