How many highways did Neanderthals build? How many rockets did they launch?
Contemporay societies have more knowledge and information,
this is not an indication of a stronger genetic pool.
Your assumptions are the same as those who believe that modern society has outgrown things like biblical laws (3000 yrs ago) and even the Constitution (230 yrs ago),
because we’re “so much smarter now” than then.
“How many highways did Neanderthals build? How many rockets did they launch?”
Thats not the point. The point is that the human race is physically becoming weaker and weaker,.
