Men with deep voices father more babies

Now this one's interesting...

According to a recent study, men with deep toned voices tend to father more children than their high-pitched counterparts.

Coren Apicella, a Harvard University anthropology student, spent six months studying the Hadza, a nomadic hunter-gatherer population from Tanzania. For her, they were ideal because they "provide a window to our past."

Hadza still sleep under the stars. Women gather berries and tubers while men hunt using the bow and the arrow. The Hadza are monogamous (but divorce rate is high) and they choose their own partners. They don't use birth control methods either, so they are what we can call a natural fertility population.

The study was pretty simple. It involved collecting voice recordings of 49 men and 52 women between ages 18 to 55 from nine different camps. They were made to say "Hujambo", meaning "hello" into a microphone.

Some analysis here, analysis there, and the conclusion (or maybe speculation?) was this. The reason why men with deep voices fathered more children is probably because they attract more women with their voice than their tenor counterpart.

Hmmm...
