Evolving views: A new look at the Scopes Trial A new book by Emory evolutionary biologist Harold Gouzoules and his son, Alexander, a legal scholar and Emory alumnus, marks the centenary of a famous trial over the right to teach evolution.

I can't wait to read this timely new book written by my dear friend and colleague and his son.

I was on a subway with Evander Holyfield and when we got off I gave him directions to the basketball arena

Sex and Gender This open access book provides an interdisciplinary perspective on the study of sex and gender and suggests directions for future research in this field.

🚨New open access book!

To promote informed applications in research, policy, medicine, and public health, the Ernst Strüngmann Forum convened scholars from diverse fields to examine a widely held assumption that sex and gender are conceptually separate.

Getting ready to #standupforscience2025

STAND UP FOR SCIENCE March 7, 2025. Washington DC and nationwide. Because science is for everyone.

Science needs bold action, and now is the time to step up. Find your city, spread the word, and take a stand.

Thank you @laurahelmuth.bsky.social for paving the way for me to share my work with a broad audience.

Sexual diversity within species is an evolutionary adaptation—a feature, not a bug.

The whole point of sexual reproduction is to generate diversity. The different pathways by which bodies develop as male, female, both or neither are never-ending. Every newly evolved way to develop into a sexed body begins a new, generative process that gives rise to still newer routes.

This Backyard Bird Has a Lot to Teach Us about Sex Variability White-throated Sparrows demonstrate that traits we usually associate with sex can be influenced by genes that are not on sex chromosomes

Do white-throated sparrows have four sexes? This bird challenges us to think carefully about what "sex" even means. Check out this article in Scientific American for my two cents: sex means many different things.

It has never been more important to take a stand.

A breeding ruff male (Calidris pugnax) in alert posture scans the breeding area for mating opportunities at Liminka Bay, Finland. Ruff males deploy one of three mating tactics that differ in aggressive and courtship behaviors. Differences in aggression between tactics are tied to concentrations of circulating androgens, which are modulated by the actions of a single gene.

A single gene underlies male mating morphs in ruff sandpipers, a new Science study finds. The results show how evolutionary changes in a single gene's structure, sequence, and regulation can drive significant diversity within a single species.

It is indeed real and wonderful!
If you'd like to learn more about sex and gender in the animal kingdom, I highly recommend QUEER DUCKS by Eliot Schrefer.

From Cell editor, Isabel Goldman: "Today is a landmark day for trans, intersex and gender diverse people, as the one of the world’s premier biology journals addresses outmoded and harmful essentialist and binary concepts of sex and gender."

The AABA... stand together against the escalating legislation and governance in the United States and across the globe that attacks the existence of transgender, non-binary, and gender-diverse peoples. We affirm the power of all persons to make the ultimate decisions over what happens to our/their own bodies. We oppose legislation that is rooted in and maintains rigid binary conceptions of sex and gender which impact reproductive justice and access to care for everyone. We condemn the biological essentialism driving much of this legislation. As biological anthropologists, we condemn the historical role of our discipline in producing binaries of sex, gender, and sexuality and are committed to work that enacts a more livable world. We condemn discrimination and denial of healthcare for youth and adults, including care that is gender and life affirming. We stand for the lives of transgender, non-binary, gender and sex diverse, and queer communities.

The American Association of Biological Anthropologists affirms our support of trans lives. Please see the full text at bioanth.org/about/positi...

Fig. 1. Dynamic sex variability - An integrative, multidimensional framework. A framework that centers sex variability will enable the study of sex across multiple levels of biological analysis (colored boxes). A) Visual schematic representing the degree of sex variability (y-axis) across biological scale (x-axis) and time (z-axis), with example sex variables of interest (not all possible covariates and functional relationships are presented). In this example, to decipher mechanisms linking gonadal hormones to receptive reproductive behavior in adult rodents (lordosis), the functional relationships (black subset of possible gray relationships) between select variables (bold words) need to be identified. At each level of analysis, numerous variables differ across sex to contribute to reproductive behavior through these functional interactions. Importantly, the degree of variability across sex categories is dynamic and is affected by developmental stage, experience, and environment.

Fig. 2. Approaches for the statistical analysis of sex-associated traits. Flow chart of example approaches for analyzing datasets with sex-associated variables. These analyses answer questions about whether and how sex-associated variables explain variation in dependent variables of interest, how independent variables of interest explain variation in dependent sex-associated variables, and how sex-associated variables (within and/or across levels of analysis) relate to one another. The examples match those in the text where possible, but the approaches are widely applicable and flexible. The choice(s) of analyses should follow directly from the research question(s), and it is likely that multiple approaches will be used in the analysis of an integrative dataset.

Fig. 3. Questions for evaluating frameworks and approaches which study sex variability and diversity. Here, we present a set of questions to ask when critically evaluating work (whether it is your own or others) that addresses sex diversity and variability. Note that these questions reflect the integration of the conceptual framework, experimental approaches, and analysis and interpretation, as each of these aspects informs the other.

The sex binary is dead!
Long live sex diversity & variability!
