Anyone trying to sell you on selective evolution is either ignorant or has an ulterior motive. There's a reason people tend to hear, "Racism!" when this sort of thing gets said -- it's not based at all in science, so what else would it be based in?
- jerf 5y agoI'm not talking about "breeding" humans as a deliberate process; I used the term in the passive sense that evolution ever "breeds" anything. I'm saying, evolution is still functioning. Who has children and what happens to those children is not uniform simply because some illnesses that used to kill us are now survivable. That was never the only effect on our evolution anyhow, merely a particularly visible one. Many other effects are still in play. It's a myth that evolution has been shut down just because one particular mechanism has been partially blunted. Certainly the net effect has been a population explosion of late, but that's still only on a short evolutionary time frame (and we kinda already know that it can't continue much longer, re: climate change and such), but that doesn't mean every fertilized egg is surviving completely undifferentiated from any other, nor that there are any other selection processes in play.
