My central case study is the controversy around the Turkana Lake molluscan fossils, presented in 1981 as representing a case of punctuated equilibrium. I show that the discussion that followed reflected wider disagreements regarding the standards for evolutionary biology. (🖼️ Williamson, 1981)

Today @dsbrooks.bsky.social and I hosted our symposium about conceptual ambiguity at #epsa25, with talks by us, Freek Oude Maatman and Markus Eronen (no pictures of me but you can see my intro slide) 😉

yesterday at #ishpssb2025‬ I presented my work on JM Rendel's attempts to reunite genetics and developmental biology!

I was thrilled to take part in the 43rd Altenberg workshop on Conrad Hal Waddington at the KLI! Thanks to @alejandrofabregastejeda.com and @fvergara-silva.bsky.social for being such great organizers! (pun very much intended)
