Canadian boffins say they have discovered a strange form of microbe living in remote Arctic springs which would, if taken to some parts of Mars, be able to survive there.

Did extremophiles evolve in such harsh environments?
Or did they evolve in more benign places and then move to the harsher places?
If the latter then it would be hard for them to get started on Mars - unless of course the "warn, wet" theory of it''s past is true.
I say that with tongue in cheek.
Truly, I wonder how the ethical debates would go, should humanity develop some plausible means for beginning to terraform another planet - taking, with some cuation, the proposition that they've discovered just that.
Technically, I suppose it would involve a small army of robotic gardeners, let alone the means to transport and deliver the microbes to our next planetary cousin. Of course, the robotic gardeners would be easier to control, from a station in orbit around the red planet.
But don't let met crowd anyone's smartypants feelings. It's just a thought, after all.
