Its a great question to pose... it makes you really think because not only is it a complicated question with a compicated answer you can also take the question different ways.... i say that there will be evolving to do until the world is at complete peace.... a good way to look at it is that the world and all aspects of it are puzzle peices that don't fit.... as time passes the pieces bump into each other and break apart and sometimes the the broken pieces attach to other pieces.... this breaking and mending is the metaphor for human evolution... when the puzzle is complete and all the pieces fit the world with be at piece and all human evolution will be complete
