Indeed. And I guess a human of 10,000 years ago isn't genetically as different as a human of, say, 20,000 years ago.
And what happened, is that humans have invented writing.
Our genetic code only carries so much useful information. Every new generation has to physically learn what the previous generations have learned the hard way, through experience. Instinctive knowledge is only useful up to a point, and will not put a man on the moon.
The human species is the first species to stockpile knowledge outside the restrictions of our DNA. We call it a library, and it carries tons of information from generation to generation. Imagine if each and every generation had to invent calculus for themselves. Today, you merely go to the library and read about Newton, and there you go.
I don't think polygamy or monogamy has anything to do with what you propose; I suspect the "magic bullet" that lead humanity (genetically almost identical to our ancient primitive ancestors from thousands of years ago) to achieve greatness (like landing on the moon) is merely the ability to do what I'm doing now, and what you're doing right now. I'm able to write, and you're able to read it. And right there, exactly the thing we're busy with
right now, is what makes humans great, if not awesome - and eventualyl leads to such cool things as moon landings.
