Why is the birth rate at an all-time low?
Didn’t say the impulse to engage in the act corresponds to increased reproduction. Take away birth control measures, then see what happens!
And you still have to be born with a pair, which in evaluating many [but not all thank God] my daughters’ male friends, is questionable at best. But I think that’s attributable to upbringing and widespread consumption of electronic diversions.
Why is the birth rate at an all-time low?
Because men are driven by their own biology to engage in behavior which, throughout most of time, has tended to result in reproduction.
Or are you attempting to imply that the current low birth rate in most Western countries refutes Darwin?
