Join anthropologist David Puts as we explore the origins of human sexuality by looking at the evolution of sexual differences in the human voice.
The roar of the male lion may indeed scare away his rivals, but it might also attract female lions looking for a dominant mate. This is sexual selection in action! The lion with the mighty roar might have a few more opportunities to pass along his genes than the lion with the less impressive voice.
Scientists have found that studying the human voice is also a good way to gain insight into human sexual selection. The human voice is highly differentiated between the sexes, and the differences are easily quantifiable. Thus it is an ideal model for understanding the evolutionary processes behind our sexual selection.
Why do human males often have deep voices? What does the human female voice signal to potential mates? Join us on February 16th for Being Human: Speaking of Sex…. and learn more about where our voices came from.
Dr. David Puts is an Associate Professor of Anthropology and member of the Centers for Brain, Behavior, and Cognition (CBBC) and Human Evolution and Diversity (CHED) at The Pennsylvania State University. His laboratory investigates the roles of sex hormones, genetics, and sexual selection in shaping human anatomy, psychology, and behavior. He has published more than 80 articles and chapters in such journals as Evolution and Human Behavior, Nature Neuroscience, Proceedings of the National Academy of Sciences, Hormones and Behavior, PLOS Genetics, and Proceedings of the Royal Society B: Biological Sciences. Dr. Puts is Co-Editor of the journal Evolutionary Psychology and is Editorial Board member of the journals Adaptive Human Behavior and Physiology, Archives of Sexual Behavior, Evolutionary Psychological Science, Evolution and Human Behavior, and Hormones and Behavior. His textbook The Evolution of Human Sexuality: An Anthropological Perspective (2009, Kendall/Hunt) is in its 2nd edition. He received the New Investigator Award (2004), Margo Wilson Award (2010), and Early Career Award for Distinguished Scientific Contribution (2013) from the Human Behavior and Evolution Society, and his research has been featured in such media outlets as Discovery Channel, BBC radio, Men’s Health, National Public Radio, and The Economist.
Running. Some people love it, getting in the zone and enjoying that “runner’s high”. Some people tolerate it as a necessary way to stay fit. Others, and I admit I’m in this camp, can’t see the appeal, unless they’re being chased by some terrifying beast or a swarm of bees….
Why did humans become such efficient long-distance runners? How can runners avoid injury? Join Daniel Lieberman on July 28th for Being Human: Born and Evolved to Run and learn about the evolution of endurance running.
