Deep Thoughts on Attraction
Apicella found the women preferred the men with the lower voices.
And that paralleled another of her findings. The Hadza men with deeper voices also had more children than their squeaky counterparts. But she says voice alone probably doesn't explain that.
...if only because of the twist on said conventional wisdom found in another article on the same study:
"We found that men with deep voices have more children than their high-pitched counterparts," Apicella told AFP.
"But those children were not necessarily healthier, so it doesn't seem like deep-voiced men are passing on good genes to their offspring, as has been hypothesized in the past, but probably has to do with them having greater access to women."
I'd be more worried about the implications of this question, except that I'm still struggling to figure out just what the heck the French babies pictured on the second article have to do with the Tanzanian men & women of the study...
