Good thing we retain the option of listening.
This explains alot...
I hve a co-worker like that.
Comes from the caveman days, I'll bet.
Women-types spending their days near the cave, in the bushes and brambles searching for berries and seeds and nuts. So, as they keep talking, they
(1) tell everybody around they are OK
(2) can hear the kids and tell what the kids are doing
(3) the kids can hear them and know where to go for help and milk and protection
(4) the noise scares away the (unfriendly) nearby animals and bears and wild pigs and predators who would otherwise be eating the non-talkiative women-type.
(5) tell the nearby people (children and women) where they are - important if you can't see without glasses and in the bushes.
So a talkative blabby gossipy woman tends to protect the nearby women and children from harm.
OK. Makes sense. Quiet silent-type women get eaten. And can't eat as much since their neighbors are being eaten. And are more likely to lose their kids, or have their kids get eaten. Noisy women who smell nice and look pretty are well-liked, and able to breed more easily. Eat more easily.
Now, think about the guys, out in the bushes trying to sneak up on a deer or pig or wild turkey or squirrel. Or avoid getting killed by raiding tribes intent on theft and murder. Or to attack and kill a raiding tribe of warriers.
Noisy, talkative, perfumed guy who's overly worried about appearances or impressions or his clothes scares away the food. Scares away the other hunters. Alerts the target that men are present.
Irritates the other hunters.
Get shot himself. Or just excluded from the next hunt. In any event, noisy feminine type guys don't eat as much, nor as often.
Survival of the noisiest (woman). Survival of the quietest (man).
