Birmingham is the city where J.R.R. Tolkien spent his childhood. I had a really nice morning walk. I’ll take a short break and then check out and head Japan. Bye-bye! #SVP2025

The welcome reception last night was great. We held it right at the foot of Chamberlain Tower, which is said to have inspired Barad-dûr. A real treat for any Tolkien fan!

I’m currently at SVP in Birmingham! On the final day, in the skull symposium, I’ll be giving a talk showing that the mammalian face is an evolutionary novelty that arose by overriding the ancestral jaw framework — and that the mammalian premaxilla is the septomaxilla. #SVP2025 #2025SVP

Huge thanks to everyone who joined our symposium at the Society of Evolutionary Studies, Japan!
Nagahama was such a charming city — classic streets and great food.
Next up: I’ll be speaking at the Society of Vertebrate Paleontology (SVP) symposium. See you in Birmingham this November! #SVP2025

This week, the Society for the Evolutionary Study, Japan (SESJ2025) will be held at Nagahama Institute of Bio-Science and Technology.
I am organizing a symposium with three guest speakers on the theme of "Theory, Plant, and Animal── Evolvability of Morphology." (in Japanese)

So, when the wings are open, he sees it as a butterfly. But when they’re closed, it depends—his answer changes based on what he saw before.
Conclusion. Kallima’s mimicry is still safe—even from tiny human predators.

Quick and certain. Was mimicry useless against toddlers? I wasn’t sure. Later that day, we went outside. He was happily picking up brown leaves, shouting “happa! happa!🌿” I showed him the same photo again.

My 1-year-old recently learned two important words: happa (leaf) and chōcho (butterfly). So I took the chance to test him—with one of nature’s greatest masquerade: the dead-leaf butterfly, Kallima inachus. I showed him a specimen. He looked at it silently for about five seconds…

I'll be teaching the course 'Animal Body and Evolution A & B' again this year as a part-time lecturer at Musashino Art University. It starts in the fall semester. Looking forward to it!
今年度も非常勤講師として、#武蔵野美術大学の講義、『動物の身体と進化 A・B』を担当します。後期からですが、よろしくね。

Our article on the anatomy of the hagfish has received enough views to be ranked as a Top Viewed Article of the Anatomical Record.

論文のデータはほぼFirst authorの 村松さん（当時・静岡大学）によるものです。もちろん私も解剖して確認しましたが。妙な縁から始まった話でしたが、立派な論文になりましたね。おめでとうMuramatsu-san！
