I doubt it. If evolution really needed death then why does an immortal jelly-fish (http://en.wikipedia.org/wiki/Turritopsis_nutricula) exist? Granted their final life stage is a polyp which creates a new young medusa, but there theoretically could be a specimen that is 7 millions years old. Either way they wouldn't need to change for number of generations.
