I doubt it. Language and human evolution operate on different time scales. We wouldn't be able to converse with someone from 13th century England. If anything I will expect selective pressure on languages—those that are easy to use are more likely to be adopted. Secondarily, I would expect this effect to be swamped by other factors (e.g. conquest).
