Tree of Sex @treeofsex.bsky.social · 19/08/2026
New publication alert: Tree of Sex 2.0 members unpack the many, sometimes overlapping, sometimes conflicting uses of "sex" in biology. Lead author Caitlin McDonough-Goldstein @ideaspermatheca.bsky.social has an excellent explainer thread if you want a preview!

Let me invite you to some cool posters this upcoming poster session at #ESEB2025 P02.034 - Sam Ebdon on faster X meeting whacky reproduction in globular springtails P02.201 - @jamesimcc.bsky.social on genome evolution of Sedges P02.049 - and myself about evolution of dipteran karyotypes

Contrasting Evolutionary Trajectories Under Paternal Genome Elimination in Male and Female Citrus Mealybugs
Most studies of sex-biased genes explore their evolution in familiar chromosomal sex determination systems, leaving the evolution of sex differences under alternative reproductive systems unknown. He...

We now have a starter pack for the Tree of Sex consortium! Interested in reproduction (not just sex) in eukaryotes? Get involved! Many thanks to @ajmongue.bsky.social for putting this together!

Fellow Europeans, it's time to move away from using American technology and software. Using European and open source alternatives makes us more sovereign and safe, and reduces the influence of Trump-supporting technology oligarchy. Here's a good guide for finding European alternatives.

If you're interested in the evolution of sex determination, check out this opinion piece from Tom Kocher, @tonygamble.bsky.social , @behrenskristen.bsky.social , Will Gammerdinger, and me. We argue that genetic variation in sex determination is probably more prevalent that most people think.

Yes, polygenic sex determination is a thing!
The process of sexual development in animals is modulated by a variety of mechanisms. Some species respond to environmental cues, while, in others, sex determination is thought to be controlled by a s...

There are a lot of new people here, so I've set up a starter pack on Mating Systems, including sexual selection and conflict, sex differences and determination. Let me know if you want to be added! go.bsky.app/QXrYoQY

Genetics Starter Pack 2 Some accounts I can’t believe I missed the first time, self-nominees, and recent arrivals. If I still missed you, I’m probably sorry. Maybe you can post starter pack 3. go.bsky.app/NvYujq4

Elon Musk answers to the Foundation Drive "Wikipedia is not for sale" asking "Have you ever wondered why the Wikimedia Foundation wants so much money? [...] So, what's the money for?"

The Onion @theonion.com · 13/10/2023
Let us be clear: This is a fraught moment, and one that has polarized not only Americans but people all over the world. It demands incredible sensitivity and strict adherence to journalistic standards of objectivity, and simply put, that is something we aren’t willing to do.
