Good one found via Cosmocking:

It's fundamental to infant survival that a mother be able to react calmly and think on her feet in a crisis situation." [...] Back in prehistoric times she would need to have the wherewithal to grab the kids and run from a predator--becoming hysterical would quite literally be the kiss of death. And it's just as important today: showing you can stay levelheaded when minor things go wrong proves to him that you're a strong, capable woman he can trust with the kiddies.

So basically, it's an evolutionary advantage to not be an idiot (though if that was true, experience would call the entire theory of evolution into question) and men find that attractive. Makes total sense.
