Peter Gray and Alex Straftis (both Anthropology), along with UNLV alum Timothy McHale, '17 PhD Anthropology, and other colleagues, published a review paper on human reproductive behavior, life history, and testosterone as part of a 30-year anniversary special issue in the journal Hormones and Behavior devoted to the "Challenge Hypothesis." The "Challenge Hypothesis" was advanced in 1990 by John Wingfield and colleagues to help organize an understanding of testosterone and male social behavior in birds. It has since been extended to many other taxa, including humans. The paper includes a citation analysis of the relevant human literature, review of findings across the life course, and extension to clinical testosterone administration. Straftis is a graduate student.
