This one is for people interested in theories about life on other planets.
At Britain’s Telegraph (November 04, 2009), Tom Chivers advises that “Darwinian evolutionary theory will help find alien life, says Nasa scientist.”
Charles Darwin’s theory of evolution, we are told, “may give pointers in the search for alien life, says a Nasa astrobiologist.”
We learn two competing views:
And so the limits of Darwinian evolution will define the range of planets that can support life – at least Earth-like life.”
… alien life may not be entirely Earth-like. Dr Baross said: “I’d like to point out there are many different ways for non-Earth-like life to not use light or chemical energy but use some other form like radiation energy, wave energy, or ultraviolet energy.”
And then how can we know that they proceed by Darwinian evolution?
So, for a free copy of the Privileged Planet DVD, about the uniqueness of Earth, provide the clearest and most useful answer to this question: Would any theory about the evolution of life on Earth predict the course of life on other planets, and if so which one and why?
