Very excited that I have a new preprint out today on how zoologists need to rethink how we conceptualize "sex"- not as a single fixed variable, but as a set of overlapping, not necessarily linked, and often multimodal phenotypes.

Huge thanks to my coauthors on this- Sara, Kinsey, and I had many many productive writing sessions over Zoom to bring this to life, and our wonderful undergrad coauthors did the bulk of the literature search along with bringing in their own great insights. I'll share more when we have the full peer-reviewed version out, but for now, enjoy!

But doesn't that make "sex assigned at birth" an arbitrary, ideological concept?

@EricLawton so for this paper we really want to focus on the applications in zoology, but to me personally based on this reasoning, yes, it's an assignment based solely on our perceptions of a couple of variables, and which ones we use is indeed a societally determined choice in many ways.
