I think this is totally natural evolution. Our technology is an extension
of our phenotype, just culturally expressed rather than genetically, and
since it lets us access a new environment it makes biological sense that we
adapt to that environment. We might need to tinker a bit before we can cope
with a near-vacuum though.
