Deeper voice pitch predicts reproductive success!
« on: January 07, 2008, 04:50:06 PM »
Deeper voice pitch predicts reproductive success in male hunter-gatherers, according to a new study from researchers with Harvard University, McMaster University, and Florida State University.

This is the first study to examine the correlation between voice pitch and child-bearing success, and the results point to a role for voice pitch in Darwinian fitness in humans.

The study, published online this week in the journal Biology Letters, was led by Coren Apicella, a doctoral candidate in the Department of Anthropology in the Faculty of Arts and Sciences (FAS) at Harvard University, with David Feinberg of McMaster University and Frank Marlowe of Florida State University.

“The results of this study have implications for the evolution of vocal dimorphism,” said Apicella. “While we don’t know the exact reason that these men with deeper voices have fathered more children, it may be that they have increased access to mates, begin reproducing at an earlier age, or their wives have shorter interbirth intervals because they provide more food to them.”

The anthropologists studied the reproductive patterns of the Hadza, a Tanzanian hunter-gatherer tribe that lives much the same way that most human beings did 200,000 years ago. According to Apicella, the Hadza were chosen because they provide a window to our past. The females gather berries and dig for tubers, while the males hunt animals and collect honey. Marriages are not arranged, so that men and women choose their own spouses. The Hadza are monogamous, but extramarital affairs are common, and the divorce rate is high.

For the study, voice recordings were collected from 49 men and 52 women between the ages of 18 and 55 in nine different Hadza camps. Participants provided the names of children born to them, whether surviving or deceased, and were then recorded speaking the Swahili word for "hello" into a microphone. These vocal recordings were analyzed for fundamental frequency.

The researchers found that, controlling for age, males with lower vocal pitch had more surviving children. Lower voice pitch did not have an effect on the number of deceased children; however, men with lower voice pitch were found to have fathered more total children, leading to a greater number of surviving children.

It was previously known that women find deeper male voices more attractive, especially during the more fertile phase of their menstrual cycle, but understanding the relationship between mate preferences and fertility is difficult in most modern populations because of the widespread use of birth control methods. The Hadza, however, do not employ birth control methods, and therefore reproductive success corresponds directly with natural fertility.

Hadza females may choose mates with deeper voices because they are perceived to be better providers, according to the researchers. Previous studies have also shown a relationship between testosterone and deeper vocal pitch, and so increased testosterone may contribute to the male's ability to hunt. Because of their similarity to the hunter-gatherer lifestyle of our ancestors, the Hadza’s reproductive success could be indicative of the way that human beings evolved.

“It’s possible that vocal dimorphism has evolved over thousands of years, partly due to mate selection,” said Apicella. “Perhaps at one time, men and women's voices were closer in pitch than they are today.”

I hate the sound of my voice when I hear it on a recording. I am currently working on making it deeper so that I can improve my reproductive success!
