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 The innate versus acquired dichotomy is outdated and has been for a long time.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...
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.

Rubber arm illusion in octopus
The feeling of a body as belonging to oneself is called the sense of body ownership
and the centerpiece of conscious experience. Kawashima and Ikeda investigated the

Been really enjoying the Complexity Science Discussion Group hosted by Paul Middlebrooks, where we're working our way through the Santa Fe Institute's "Classic Papers in Complexity Science". The group is open for anyone interested:

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...
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.

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. 🧪

Temporal integration and decision-making in crocodiles
Summary: Crocodiles' attraction to two sensory stimuli (water vibration and airborne sound) is independent of the order of arrival of these stimuli, within the limit of a certain time window.

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”
I know it's a rough time to be talking science, but in case anyone wants some distraction, I wrote about the Tan et al (2024) analysis of heritability and polygenic indices for complex human behavior. Title: Is Tan et al The End of Social Science Genomics?
