re: #58 Daniel Ballard

I think there would be time to go through that cycle many times. Evolution=millions of years, remaining life of our sun & earth at about this distance=billions of years. We are the rookie squad of intelligent beings. Of course if we kill ourselves we should lose the intelligent title.

There’s no reason to assume it would happen again. It all depends on what niches different organisms find themselves in, and how they can better adapt to that niche. Intelligence is the adaptation, not the niche.
