The preliminary programme for @ces2026.bsky.social is now out. What a fabulous line up!

Print screen of the article title and the abstract "AI, Human Cognition and Knowledge Collapse"

Punctuated equilibrium of stalled cultural-evolutionary progress as a side effect of the emergence of accurate AI models. Reminds me ideas of Sergi Valverde @svalver.bsky.social . Could we call it the ultimate imitation regime? When you loose the intellectual wandering.

Reproduction of multicellular organisms emerges as an exaptation of their ecology

Conformity and individual preference shape nest material use in zebra finches (Taeniopygia guttata) Culture, learned behaviours shared within a group, is found in diverse species and critically impacts fitness. Culture arises through social learning and persists when newcomers adopt group norms via…

A new study by @julself.bsky.social and colleagues reports that male zebra finches balance social conformity and individual preference when selecting nest materials.

Many thanks for sharing your work; I’ll definitely read your book.

I believe that the best ideas emerge from a state of calm, as well as the freedom to explore without the external pressures of grant hunting and its risks. Enjoy!

Demographic shifts, inter-group contact and environmental conditions drive language extinction and diversification.

Many thanks also to @elena-moos.bsky.social, who just joined bsky. Elena was the master knapper in the new study who made the application of the new method possible.

Follow Elena, and I am sure you'll see amazing stone tools (and even dice!) made by her.

Friends in Edinburgh!

Join me on June 27, as I unveil The Story of Birds at our wonderful local bookshop, Toppings.

Get your tickets early here!

Thanks for the invitation — a very interesting synthesis.

One angle for a commentary could be tinkering under ecological and network constraints, especially in software and technological systems. I’d be happy to contribute from a complex-systems perspective if useful.

Thanks @replicatedtypo.bsky.social for pointing this out.

For a more informal overview of the intuition — including the ecological implications — I also wrote a short Bluesky thread here:

Nice to see “tinkering” being highlighted in cultural evolution.

We recently published a chapter synthesizing our work on tinkering-based models of software and technological evolution.

The growing convergence suggests this idea is now part of our shared toolkit. @culturalevolsoc.bsky.social

Thank you, James.

As a side point: the term "tinkering" is not even new in the context of cultural evolution -- Francois Jacob had a paper on this in 1977 called "Evolution and tinkering" and @svalver.bsky.social + colleagues directly refer to tinkering in their papers on tech evolution

Interesting! Is there any connection between "Top Speed" and "Special Criminal Investigation" (both from Taito)?

Very happy to see our ice-fishing paper on the cover of @science.org this week! 🎣🎉

We tracked large groups of Finnish competitive ice-fishers to study how social foragers use social information when searching for resources. 🐟

Sun rising behind a mountain. In the foreground, two strings demarcate the edges of an ancient monumental road that lines up with the sunrise.

Happy #WinterSolstice ❄️

In Chaco Canyon in the US Southwest, ancient monumental roads align with the winter solstice sunrise over Mount Taylor. Features of both land and sky were (and still are) ritually important to the region's Indigenous people.

Achieving true interdisciplinarity is hard! @shumon.bsky.social makes an argument for accepting the transformative nature of #interdisciplinary research - even if that means researchers must revisit their standard methods and assumptions!

Imagine you have no clue that there is an entire universe of people with diverse capabilities centering on the generation of new ideas and the refinment of old ones.

I dislike that Time Magazine has chosen to conflate CEOs with the people who actually got their hands dirty making the technology work.

I’m incensed that Fei Fei Li is half off the page. I’m sure she is too gracious to say it.

I’d like to thank Stuart Newman for his editorial work in one of my favorite journals these days. Biological Theory is one of the few journals that takes seriously the intersection between empirical and theoretical approaches to biology. I wish the best to Kevin Lala in his new role as editor.
