Re: Prometheus, Continued
Thanks for the great post. Very interesting.
It's true that once DNA develops, life can be found virtually anywhere. A remarkable device which adapts to almost anything.
A factor left out of Drake type calculations is that while intelligence can evolve in a variety of ways, it must have the ability to express itself by manipulating the environment in meaningful ways to establish communications. Dinosaurs, birds, marine mammals, and apes have come a ways and could go farther with intelligence, but don't have an ability to influence their environment much.
As an aside, here's hoping other intelligences don't find us.
