- Reposted by Christopher B. CameronExciting news! Our invited perspectives in npj Biodiversity looks at how marine life bounced back after the worst mass extinction ever, the Permian‑Triassic Mass Extinction (PTME) ~252M years ago. Big questions: fast or slow? recovery or restructure? www.nature.com/articles/s44...

- Scene: My wife’s friends, who are chef’s in Ankara, & whom I’m never met, invited us for a visit. Friends: do you have any dietary restrictions? Me: pinworms, roundworms, & tapeworms. Friends: Me: dont get me wrong, I’m pro-worm. Friends: Wife: He’s a down-to-earth guy. I love her so much.

- Interesting article, but the role of dead corals in the establishment of healthy young corals is more complex than it is presented here. For example, the decay of dead, outer reef, hard corals is perilous for the garden varieties that depend on them to break waves and modulate flow.

- The colonial tubariums of #hemichordate graptolites are the most disparate secreted matrix structures in the history of nature. The genus #Rhabdopleura emerged in the mid-Cambrian & persists today. Soon, I will reveal the chemical composition of its tubes. The project has driven me mad. Stay tuned!
- As #Alberta & Québec #separatists seek referendums, realize that this is #colonialism - separatists seek to govern indigenous land & people against their consent. Separatists sideline 1st Nations who best know the land, who have much to offer in effective law, good governance, language & culture.

- My most effective exam question? I ask students to provide an example of something (eg, heterochrony, heterotopy, heterometry or heterotypy) from the literature. Then, discuss their findings with me before exam day. It's a fun method to engage in critical thinking & composition. 🚀 #pedagogy
