Evolution and Human Behavior Lab

Welcome

Welcome to the Evolution and Human Behavior Lab! An evolutionary perspective provides a unifying lens for understanding human behavior. Our hominin forebears have undergone important shifts in subsistence, coalitions, mating behavior, parenting and much more in the past few million years. We’re interested in addressing how human cognition, behavior and physiology play out across various socio-ecologies in the world today. We believe that the best of this kind of integrative research attempts to combine the latest in interdisciplinary evolutionary theory; findings from comparative animal research; naturalistic observational studies and behavioral methods; places human behavior in social context, also employing life history theory to do so; and considers function in addition to physiological mechanisms, development, and phylogeny. Please browse the lab website and let us know if this is a place where you might find a research or exploratory place.

Research

Dr. Peter Gray engages in evolutionary-inspired research on human reproduction. In practice, this means devoting much of his teaching and research to central concerns in human sexuality, parenting, and family dynamics, both in the Caribbean (Jamaica and St. Kitts) and the U.S. As more pets have been viewed as family members, this has opened new avenues for human-animal interaction possibilities too. Gray engages in work on human behavioral endocrinology, with limited capacity for salivary steroid assays at UNLV.

Please email Dr. Gray if you are a prospective graduate student with overlapping areas of interest in graduate school, or you are a current graduate student or advanced undergraduate student at UNLV and would like to participate in a weekly, informal, interdisciplinary lab reading group. Graduate student lab group members include A'liciah Carr, Lyndsey Craig, Elizabeth Johnson and Alex Straftis, with other graduate students regularly involved and welcomed. Undergraduate student participants and researchers include Kari Goold and Jorge Paiz-Say. The research interests of past and present student lab members run a wide gamut, and include:

  • PCOS among women in Delhi, India
  • Sexuality of postpartum nursing mothers in Manila, Philippines
  • Women’s responses to sexual infidelity in Jamaica
  • Boys’ hormone responses to competition in Hong Kong
  • Men’s testosterone responses to poker competition
  • Men’s testosterone, cortisol, DHEA, androstenedione and aldosterone responses to playing League of Legends
  • Cross-cultural approaches to human-pet dynamics
  • Mate preferences among single mothers
  • Content coding of websites marketing testosterone supplementation
  • In varied cultural contexts, investigating men's experiences on prescription testosterone
  • Pubic hair removal practices in cross-cultural perspective

For graduate students, there are excellent opportunities for integrative training in concert with other departmental faculty. This is of benefit when organizing a thesis or dissertation committee and when seeking broad training combining perspectives of evolutionary psychology, human behavioral ecology, human behavioral endocrinology, evolutionary and life history theory, Developmental Origins of Health and Disease (DOHaD), the hominin and fossil archaeological record, the evidence and influences of animal domestication, ethnographic methods, cross-cultural comparisons, and applied human health.

A number of other UNLV Anthropology faculty provide expertise contributing to an understanding of evolution and human behavior. Dr. Alyssa Crittenden conducts research with the Hadza, hunter-gatherers of Tanzania, and addresses a variety of research topics on childhood, nutrition, and social behavior. Dr. Pierre Lienard conducts research on the evolution of human cognition, with an emphasis on ritual, risk, and social behavior. Dr. Bill Jankowiak employs evolutionary and cross-cultural perspectives to help integrate findings from long-term ethnographic field research in urban China and within a U.S. polygynous Mormon community, in addition to a variety of Las Vegas projects related to human sex differences, romantic love, and sexuality. Dr. Ivan Sandoval-Cervantes engages in research on human-dog dynamics, and provides field methodological expertise. Dr. Dan Benyshek has conducted research concerning the etiology and ethnographic context of metabolic health problems among Native American communities in addition to lab-based experimental rodent studies designed to address causal mechanisms and developmental pathways underlying metabolic disorders. Dr. Brian Villmoare engages in research on hominins, particularly Australopithecus in Ethiopia, and also has interests in the evolution of hominin social behavior. Other faculty such as Dr. Debra Martin (bioarchaeology), Dr. Levent Atici (origins of agriculture), and Dr. Liam Frink (hunter-gatherers) offer courses that contribute to an integrative training program focused on the evolution of human behavior.)

Publications and Media

A list of publications by Dr. Peter Gray can be found in his CV.

Research by Dr. Gray and colleagues has attracted media attention from a variety of sources, including in recent years the Las Vegas Review Journal, Washington Post, Aeon, Times of India, New Zealand Herald, ABC Online, MSN, National Geographic, Denver Post, and KNPR, among others.
