No no no, it's a genetic evolution based on mutation with how their lungs work. This isn't conforming to societal prospect.
Oh yeah that, I know what you're talking about now
I don't doubt that some changed happen based on climate change, they do. But I don't think it happens like evolution suggests.
Evolution suggests that a mutation happens, and due to climate and such, that mutation outlives the normal genetic setup, and so it continues on. Survival of the fittest. But that's not quite what happened there- people who lived there for long periods of time developed more powerful lungs to take in more air, that wasn't genetic, it was just the body's natural plasticity. Like building muscle in response to stress
Some genetic mutations do happen though, else we wouldn't have such a wide variety of dogs. I just don't think it happens on such a scale that we'd get anything other than a dog over time
