Didn't I read as recently as ten years ago that "Jurassic Park" scenarios were more or less impossible? I don't expect Neanderthal man to reappear soon, but assuming the world stays (relatively) peaceful and wealthy, what is the chance of seeing one or more such beings within the next two hundred years? Yes I know all about the law, eventual demographics, and the fear of planet-wide interspecies war, but at $10 million and over one hundred countries in the world, is not private philanthropy robust?
As one commentator asks, if we humans killed them off in the first place, does that mean we have any obligation to revive them now?
