It just seems like it would be a really cool thing to have gills and be able to populate the oceans in the same way we populate the land. We could have houses and shops and vehicles, andgo on walks/swims and just kind of live underwater.
Start a whole new second species of human here on earth maybe, Who knows?
Exactly.
We still theoretically could, I guess, but people already have enough body image problems just from getting wrinkly or kinda bald, let alone being a freak mostly made of human-skin batwings.
