“A bird with a 10-gram brain is doing pretty much the same as a chimp with a 400-gram brain,” said Onur Güntürkün, who studies brain structures at Ruhr University Bochum in Germany. “How is it possible?”
Intelligence Evolved at Least Twice in Vertebrate Animals | Quanta Magazine
Complex neural circuits likely arose independently in birds and mammals, suggesting that vertebrates evolved intelligence multiple times.

The light-sensitive tissue of birds’ eyes is not supplied with oxygen by blood vessels – instead, it powers itself with a flood of sugar, and this may have evolutionary benefits
Bird retinas work without oxygen, and now scientists know how

I'm teaching Statistical Rethinking again starting Jan 2026. This time with live lectures, divided into Beginner and Experienced sections. Will be a lot more work for me, but I hope much better for students.
I will record lectures & all will be found at this link: github.com/rmcelreath/s...

🧠🌟🐭 Excited to share some of my postdoc work on the evolution of dexterity!
We compared deer mice evolved in forest vs prairie habitats. We found that forest mice have:
(1) more corticospinal neurons (CSNs)
(2) better hand dexterity
(3) more dexterous climbing, which is linked to CSN number🧵

🧠🎓 Heute war wieder Postersession!
Erneut stellten Studierende zum Semesterabschluss ihre Studienleistungen vor, in der sie Alltagsphänomene spieltheoretisch oder verhaltensökologisch modellieren sollten.
Wir freuen uns über die vielen kreativen Ansätze und die spannenden Diskussionen! 👏

Have been asked by a proof reader to spell out what JASP is an abbreviation for in a new manuscript. Discovered it stands for Jeffrey's Amazing Statistics Program", which is now in the paper.
This makes me happy.
