Today, we explore the befuddling (and surprisingly complex) mystery of the human beard. Our guide is Dr. Barnaby Dixson, a human behavioral ecologist at the University of the Sunshine Coast who uses interdisciplinary methods to investigate human mate preferences across cultures.  His extensive work has bettered our understanding of a wide variety of physical traits; most relevant to today's discussion, he is one of the primary contributors to our understanding of beards. We discuss the evolution of facial masculinity and facial hair, and their role in attractiveness and intimidation across various contexts. You can learn more about Dixson, here: https://www.usc.edu.au/staff/dr-barnaby-dixson

Relevant sources are mostly in Dixson’s past publications: https://scholar.google.com.au/citations?user=LE_ROqQAAAAJ&hl=en

William Costello is an expert on incels, a rising star in the field of evolutionary psychology, and the latest protégé of Dr. David Buss. In this conversation, we discuss incel violence, demographics, mythology, perception vs. reality, and solutions to inceldom, among other things.

There's still time to participate in Costello's cross-sex mind-reading study, here: https://utexas.qualtrics.com/jfe/form/SV_38KyEyGDOs4stN4

Alexander is a psychologist and science communicator. He is best known for his deep dives into the literature on human mating and his nuanced critiques of popular misconceptions about dating. In this data-driven discussion, he talks to Macken about what men and women actually want and what people generally get wrong about dating, before diving into a variety of topics including the Manosphere, the “mating crisis,” hypergamy, and bodycount, among others.

Alexander is @datepsych on Twitter, where he runs online studies and produces fascinating threads on mating. He also runs a popular blog, datepsychology.com, and is increasingly popular on YouTube, @alex.datepsych.

Plomin is one of history's most important psychologists and a pioneer in the field of behavioral genetics. He is a research professor at King's College London, best known for his work on twins. In this podcast, Plomin explains how we know that genes impact our behavior, clarifies all the common confusions about the field, and pushes back against some of Macken's criticisms. Enjoy.

Women compete vigorously over mates but do so more subtly than men. In this episode, Dr. Tania Reynolds teaches us how women use gossip to win mates. Additionally, we discuss friendship, thinness, and the evolution of homosexuality, among other subjects.

Tania Reynolds is an assistant professor of Evolutionary Psychology at the University of New Mexico. Her research examines how intrasexual competition and cooperation contribute to psychological and behavioral sex differences. She investigates how pressures for humans' ancestors to select advantageous social allies—and be selected in return—contribute to modern-day preferences, biases, and behaviors.

Infidelity is almost ubiquitous among the Himba, an indigenous group of pastoralists living in Namibia and Angola. In this episode, I speak with a human behavioral ecologist who can help us understand why.

UCLA's Professor Brooke Scelza (@bascelza) has studied reproductive decision-making in these people for about a decade. Her fascinating work has made progress towards understanding the rationale behind patterns of parental investment, fosterage, and infidelity. In this podcast, we focus on the last item on this list. Come learn about an interesting culture and view infidelity through a new lens on this episode of Species.
