I wonder if future civilizations occupying a very different world would evolve over time to tolerate or even benefit from elemental differences in a new environment.
the atmosphere of Venus, even at that altitude, is mildly acidic and would irritate your eyes
For example, given enough exposure and time, could humans maybe evolve a voluntarily controlled transparent inner eyelid that could shield the eye from irritants in the atmosphere? Or with technological advances could we bypass the need for evolution by modifying/up-grading humans with cybernetic implants to survive in harsh conditions?
Skyloft ftw. What a fun and exciting idea.
