Men intuitively figure I can have another batch later. [/quote]
If that is true then they also must “intuitively figure” that that next “batch” might be a little challenging. There is mounting evidence that older men are more likely to father children with problems – autism and schizophrenia are the most notable, but the list also includes dwarfism, Marfans, etc. See: http://www.nytimes.com/2007/02/28/health/28iht-snfert.4748536.html
So if we’re talking evolutionary biology here, instincts compelling men to have kids at a younger age would be selected for, rather than selected against. In other words, logically speaking, one would not expect a man to choose to have a child at a later date if there is an opportunity to have one earlier. Plus, competition being what it has been for the last million years, men are less likely to have the opportunity at a later date, Strom Thurmond notwithstanding. So, if you are suggesting a biological basis for what you’re saying, I don’t think it works.
