Environment pressure is a huge force in Natural Selection. If the changing environment makes it so that 50% of males can't sire offspring then Natural Selection is working, right? I'm not following how this is "bottom of the barrel", this appears to be simply how Nature works.
- ironmagma 6y agoYes, but historically the environmental limitations have likely been a bit more meaningful than, "this group of males unknowingly bought product X which unknowingly contained contaminants from a grocery store," or "this group of males live near an airport."
- taylodl 6y agoNatural Selection is going to select for who's best able to survive in a man-made world. We already see that happening with animals. I'm not entirely sure this is a bad thing but simply how the entire ecosystem is evolving.
- ironmagma 6y agoRight, that's how things are, but it's not probably what should be. Man-made contraptions are hardly long-term stable or hospitable to life, including our own. Additionally, IVF bypasses natural selection since it is artificial.
