SS2025 - Sexgender diversity in biology

Logo Gender Diversity Equity Inclusion Reading Circle


"Biology is a continuum, but we biologists, because of our limitations, divide ourselves into categories, and then we pretend that those categories exist in the living systems that we study."

Bartholomew, G. A. (1958). The role of physiology in the distribution of terrestrial vertebrates. Zoogeography, 51, 81-95.


“Biological facts” are often central to current public debates about sex and gender in humans. But is biology enough to understand the complexity and variation of human sex, gender, and sexuality?  And why and how should biologists contribute to this debate? The DEI Reading Circle, organized by Women in Biology, wants to explore these topics this summer semester.

We are convinced that biologists should deeply care about this topic because it has real consequences for people’s lives as science is being weaponized to discriminate against marginalized groups. We will take a look at how we historically conceptualize and operationalize biological sex in animals and humans, and learn which biases these categories carry with them. We will also scrutinize these influences on how we do and talk about our science, and look at new concepts and frameworks beyond simplistic binary models of sex and gender to do better. Finally, we will consider how can we make teaching more inclusive with regard to sex and gender diversity content.

Summer Semester 2025 Meeting Dates and Times

We meet in the UBB Mensa in the comfy sitting area at the very back. 

Meetings start at 16:30, and last about 60-90 mins. 

The bistro closes at 17:00, so if you want to get something from them arrive a bit early. 

Before participating, please make sure you have read the ground rules so the meetings will be a respectful and safe experience for everyone.

For each meeting, we have selected a short, fast reading (~ 15min), and a longer, in depth reading for the topic. Depending on how much time you have, you can choose either one to read ahead of the meeting. And even if you did not have any time, you are welcome to participate in the discussion.

We tried to choose readings that are available without any paywalls. But in case you do not have access, please contact Caro Deimel. We can send you a link to a shared folder.
