Looks super interesting, but I can't access it through my uni. Could you send me a copy please?

What if eye...? Computationally recreating vision evolution Recreating evolution by coevolving eyes and behaviors in embodied agents allows exploration of what-if questions in vision.

Dan-Eric Nilsson & his colleagues have created virtual animals with AI vision to study evolution in a new way—watching natural selection and adaptation unfold in real time inside simulated worlds. A powerful new tool for evolutionary biology. www.science.org/doi/10.1126/...

Can also recommend, and there was a nice chapter-by-chapter reading club of it with Georg and lots of other great speakers - videos still up here:

Highly recommended! I just finished a cover-to-cover read, and it's a great addition to the avian sensory ecology literature with excellent discussions of the links between brain & behavior. I prefer reading paper books (better retention) but the whole thing is freely downloadable! bit.ly/482xPZm 🦉🧠

A graph comparing the number of neurons in the telencephalon of reptiles, birds, and two estimates for T. rex. Even the lowest of these estimates suggests the telencephalic neuron count of T. rex to be similar to that of a pygmy falcon or blackbird - several times more than the largest telencephalic neuron count of extant reptiles.

Learned use of an innate sound-meaning association in birds - Nature Ecology & Evolution Over 20 species of geographically and phylogenetically diverse bird species produce convergent whining vocalizations towards their respective brood parasites. Model presentation and playback experiments across multiple continents suggest that these learned calls provoke an innate response even among allopatric species.

This is an awe-inspiring and fascinating study that I thoroughly enjoyed reading. However, the overall framing in terms of "innate versus learned” is unnecessary. The innate versus acquired dichotomy is outdated and has been for a long time. www.nature.com/articles/s41...

It's wild coming from cognitive science to comparative cognition. In cogsci, cognitivism is largely seen as dead and has been for some 20+ years.

It is common to view cognition as being for action. In psychology too.

Yet, this is where they put the blame? The field needs more cogsci, not less.

Which Kind of Science Reform What hope is there for science reform, if we can't agree on what to reform? Right now, principles are more important than practices.

How can we reform science? I have some ideas. But I am not sure you’ll like them, because they don’t promise much. elevanth.org/blog/2025/07...

Now, some thoughts on seeing Aquilops on the big screen! "Our" little dino was one of the stars of Jurassic World, and that was quite an experience as one of the scientists behind the research. (1/n)

Why did cephalopods develop intelligence? And why, being so intelligent and cognitively complex, do they die so young? In this @cp-trendsecolevo.bsky.social ‪paper, the authors explore this paradox from an ecological and evolutionary perspective. www.cell.com/action/showP...

Our letter is out in @cp-trendscognsci.bsky.social

We argue against a recent claim that animals cannot make mental simulations because they supposedly do not reliably memorize sequences. The evidence for model-based animal cognition is too overwhelming. 🧪

A 2.5 meters long female alligator which kept her juvenile colouration. She has a dark back and a yellow underside, notably with yellow lower jaw and throat and yellow stripes on her flank. She lies serenely on the green, fake grass of an indoor enclosure, with a wall and doors in the background.

A close-up on the head of the alligator in the previous picture. She has a juvenile colouration with a dark back and a light yellow lower jaw and throat. We can see the big teeth coming out of her upper jaw and the black pupil in her dark brown eye. She lies serenely on green, fake grass of an indoor enclosure.

I did some data collection with the alligators yesterday and I took a couple of pictures of Sigi after her feeding. She was probably feeling very satisfied.

The field of behaviour genetics has turned out to be something of a damp squib: “genomic information is a statistically non-zero but all in all relatively minor contributor to behavioral differences”
