It doesn't just "sound good to me", you can watch culture and technology influence reproduction, the main driving force of evolution. For example, today we can sit for hours and thrive, while a hunter-gatherer or farmer would starve sitting around all day. Our bodies protest, but we manage to reproduce, and treat or palliate the ailments that come with sedentarism. We surely are evolving to better tolerate sedentarism, but it's slowed down because medicine allow the unfit to sedentarism to survive and reproduce instead of dying early. You can see the delay of evolution, allowing the biologically unfit to reproduce, at any hospital. Medicine saves or prolongs more lives than ever, and death is the second driving force of evolution. Stephen Hawkins, for example, was diagnosed with ALS and given two years to live, and despite that he had three descendants years after. He couldn't do physical work, but could do great mental work, which our society values. You can correctly argue that our civilization is part of the environment, though. In that case, natural evolution isn't slowing down, it's just going in a different direction than it used to. |
