Well, that feeling of wanting to have kids isn't really universal. It's not really primal, like needing to eat or something. The desire for sex pretty much is.
Is it evolved? I guess everything is evolved. Some people have the desire to abuse their children. That's evolved too some how some way, I wouldn't call that an evolutionary drive though.
I don't know if female dogs crave sex or crave puppies. If they're anything like us, the majority of the time it's the former craving that leads to puppies. That's all I know.
