Thanks for a new approach to this. I was pretty burned out on this
subject last month but I'm glad to see it reappear with an interesting
hypothesis. My own old idea, that plainly visible breasts were a survival
("don't kill me, I'm a girl") signal for invading armies, is less good.

So I'll offer a new one: Human infants take much longer to wean than
chimps; breastfeeding might have lasted several years and possibly a small
breast might quit working after a year or so. This solves the puzzle of
why all breasts today aren't the same size - some groups (regions of
Europe & Africa) nursed longer than others (China).

I can hardly believe you said that, Karen. I'm sure it's true, but it's a
rare thing to hear a sentiment like that from a girl these days. -Tom
