I think this shows a misunderstanding of what is going on. Each one of the 6 billion of us is a tiny experiment in selection. There are countless things going on that we don't see.
That briefly touches on one of my pet themes.
"Will we recognize an evolved human?"
For example, if a new way of correlating input, a new way of thinking, arose that let someone outthink others, wouold we even realize that a significant change had happened? Or would we simply ascribe it to being smater or luckier than others?
