Go forth and multiply

[Vladimir]

A moral obligation? A legal one? How? Why?

The only basis for such an obligation would be religious. Without a godly precept, man has no reason whatsoever to procreate.

Certainly no Darwinist ever said 'Go forth and multiply', even if survival were somehow a moral obligation it does not follow that multiplication is the way to go for a particular individual. Evolution works on the group level as well.

Survival depends on adaptation to (changing) circumstance. Circumstance may demand many or few children. In today's society the raising and enculturation of succesful off-spring is so labor-intensive that maybe (even probably) 'less is more'.

In short, a childless couple of lawyers who contribute the maximum to society may be more instrumental to group survival than a couple that devotes itself to kids.

Adrian, you're too intelligent for my post. I'm not talking about the human constructs of morals, laws, and whatever keeps us civilized. I'm talking about A, C, G, T. Without a godly precept, what reason does anything have to procreate?

Come on now, these are the basics.
