It depends on the root of the evolution I would say. Sure, if someone has gone through the process and achieved enlightenment like Buddha, they may be able to evolve the teachings to better fit the times. However, my gut says that is often not the case, and much of the evolution is egoic in nature at the hands of a charismatic individual who wants to fulfil their desire or lust for power. I'm far from an expert on Buddhism, but my own journey has taught me that ultimately we must kill our Buddhas and inner realization ultimately is a journey you must walk alone and discover for yourself. The teachers along the way may serve as wayfinding, but must ultimately be discarded. If the evolved state of the religion seems like a big club, and isn't serving it's members to strike out on their own on their inward journey, to achieve independence and sovereignty, it should be questioned in my opinion.
