AFAIK, it's the scienfic consensus that any huge and prosperous population can't evolve, because evolving into another species
requires huge changes in a small population in a short interval of
time. Any huge change in mankind would be suppressed by the
other 6 billion human beings. Also, probably changing to a "better"
kind of humans might require spending lots of generations into a
"much worse" kind of human, and this can't happen now.
In global terms, isn't the human population quite small?
There are plenty of fish, insect, and arachnid populations which far exceed human populations as individual species, and are for breeding purposes contiguous, but they still manage to diversify.
Or is the K/R raising differences that affect the spread of genetic chnages?
