You must mention Darwin’s idea that the female of any species is the motor of this selection by choosing the males they consider better, fitter, etc.
And over the centuries this “natural” selection has been replaced by other objectives: making money, making a profit, create a business, or become a central polar attraction in the field of ideas and ideology. In one word POWER.
What’s more for humans reproduction has become a secondary minor marginal objective of the reproductive instinct, or is in the process of becoming this all over the world with China at the spearhead of this movement.
Men with multiple wives and half a dozen or a dozen children is passé, archaic, absurd even in countries practicing polygamy.
“Natural” selection seems to be different with human beings and we are moving towards scientific laboratory genetic selection. Totally artificial, man-made.
