Quote:An earth like atmosphere would raise the temperatures and so would dense forests. 81 degrees is hardly unlivable.Yeah but my point is that the range in temperature is huge. You would have to combine a sort of tropical animal with the coat of a polar bear x2 to survive that. I'm no expert on animals or biology, but my gut feeling tells me the features a species would need to have would be pretty incompatible and useless whenever the temperature isn't at the relative value for that feature to be useful.
The (possibly) pre-existing atmosphere would have changed the entire climate though. So, who knows really!
