It wasn’t a scientific statement, nor perfectly accurate. What I mean is that typical examples of human evolutionary “progress” given do not manifest themselves in the entire population of humanity.
Things which are obviously improvements don’t wipe out the population of those without the improvements, and things that are obviously traits that make us weaker have not disappeared from our genetic pool.
Once you get past the historically documented history, we have speculation about things that have changed, but that’s what we are arguing about (like did we use to have tails). What I’m saying is if you look at the documented historical life of humanity, over the few thousands of years we have a reasonable understanding of our history, we still see today living examples of “humans” from the various “evolutionary” forms humans have taken that are clearly examples of how mutations can be selected and lead to “evolution”.
If I try specific examples I might get laughed at, but I don’t care, I’ll go ahead anyway. Like people are getting taller, but there are still lots of short people, there’s even a show about “little people” on TV.
Like aborigines and other populations of humans found that are clearly less “evolved” than “modern” man.
