That supposition is not altogether clear - seeds of life may have been asteroid/meteorite provided, in which case life on earth was evolved for different places

That supposition is not altogether clear - seeds of life may have been asteroid/meteorite provided, in which case life on earth was evolved for different places entirely.
Anyway, the Cambrian explosion shows how life can fill any ecological niche from ocean-bottom sulfur vents to mountaintops, from the stratosphere to mudpots in Yellowstone.
We don't have to wait for that. Lots of science fiction about making people to fit the world. An obvious solution, and already we're gaining the tools to do it.
