These are interesting examples. It does remind me of the evolutionary scientists talking about covid and how vaccinating the entire human population is likely to expedite the evolution of the virus due to evolutionary pressure placed by the vaccines which all target the same spike.
That should also explain why most people of today are indistinguishable from the people from 2000 thousand years ago (not a lot of evolutionary pressure). Though, there are some exceptions. I have heard scientists talk about people living high up in the mountains for many generations and referring to them as an evolved subspecies of human beings, since they developed certain physical traits which are unlike anything present in most other human beings (their ability to live and thrive in an environment with much thinner oxygen). Same could be said about eskimos - living in perpetual cold environment and eating only sea products.
Like I said before though - most people are indeed indistinguishable from the people from 2000 years ago - except for height - we are giants now, and I can't explain that with anything other than heavily modified diet and how our food is being grown these days (steroid use/genetically modified foods/etc).
If all people turn to living in the meta world (as facebook expects), I expect that to apply a pretty big evolutionary pressure as well.
