A discussion with Marta Kowal on beautification and what predicts it.
Marta Kowal (PhD) is a post-doctoral researcher at the IDN Being Human Lab, Institute of Psychology, University of Wrocław, Poland. Marta's academic background is in evolutionary psychology, and her research primarily focuses on mate attraction, physical attractiveness-enhancing behaviors, and romantic love, particularly from a cross-cultural perspective. During her PhD program, under the guidance of her supervisor, Professor Piotr Sorokowski, Marta secured a grant from the Polish National Science Centre to explore beauty-enhancing behaviors across different cultures. Marta takes one of the leadership positions in an extensive international consortium of over 400 scientists from more than 100 countries passionately committed to facilitating large-scale cross-cultural research projects.

A natural history of infidelity and a history of science on the topic. Listen and learn about the oldest known laws in history, fish that get pessismistic without their boyfriend, the costs of monogamy, the ovulatory shift hypothesis (and a conspiracy theory about it), the mate-switching vs. dual-mating debate, and so much more.

An audio essay on human nature, followed by an interview with primatologist Dr. Susan Cheyne. Susan is the co-director of the Borneo Nature Foundation International and the Borneo River Initiative for Nature Conservation and Communities, she is the Vice Chair of the IUCN Section on Small Apes, and she is also a Senior Lecturer at Oxford Brookes; she has been studying gibbons for about 27 years. Our conversation is wide-ranging, but centers on gibbons. We discuss gibbon locomotion, life among gibbons, the nature and function of gibbon song, gibbon violence, monogamy, and infanticide (and lack thereof), and other subjects. Enjoy.

A deep dive into the manosphere, with the scholar who knows it best, Louis Bachaud.
The manosphere is a constellation of 5 loosely affiliated communities, including pick-up artists (PUAs), men's rights activists (MRAs), "Men Going Their Own Way" (MGTOW), incels (the "Black Pill" communiy), and the "Red Pill" community. Louis details the history of the manosphere, describes the current factions and their differences, and guides us through their use and misuse of science, especially evolutionary psychology. The episode opens with a systematic critique of the manosphere, and the interview starts around 34 minutes in. Enjoy.

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

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.

"DNA isn't all that matters, but it matters more than everything else put together."
—Dr. Robert Plomin
Blueprint: https://mitpress.mit.edu/9780262039161/blueprint/
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.
