Let me also add: I only could briefly look this morning. Maybe the natural selection story is not as prevalent in the paper as it appeared at a glance.

Yes, the highly specific phylogenetic story "a) natural selection b) for this anatomy c) due to one behaviour" is what icks me, too.
Absent this storyline, the anatomical difference, if true, remains relevant regardless (I am not trained in anatomy, so I can't judge that claim)

"recommended for you"? Is that a channel?

There were 18/167 Influenza A infections in the intervention and 31/167 in the control. There were 39/167 influenza B infections in intervention and 28/167 in the control.
Overall lab-confirmed influenza was 57/167 vs 59/167. About as null an effect as you can imagine.

Actually, looks like you got a good discussion going here :-) but yeah, that has become rare.

So, apes clearly show cultural dependency in their cultural breadth (our new paper on diet breadth). But w.r.t. cultural *depth*, apes rarely if ever show cultural dependency. A handful or so cases may be real - though these continue to be debated.

Thank you, Bob, for the kind words.
The problem is that chimps are great innovators, also of tool use. Subtracting this innovation reach from their tool use leaves little scope for such kind of culturally dependency.
See, e.g.: onlinelibrary.wiley.com/doi/10.1111/...

The Method of Local Restriction: in search of potential great ape culture‐dependent forms
Humans possess a perhaps unique type of culture among primates called cumulative culture. In this type of culture, behavioural forms cumulate changes over time, which increases their complexity and/o....

Despite this, it looks like I could submit the abstract regardless.

Not quite sure what the question is? Johan, maybe you wanna answer?
The hypothesis is not that humans use/make/copy sequences, but that this is not a trivial thing to do.

Haha, yeah. Morning-brain and typed between coffee and shower.

The nice thing here is that clever and well controlled and well reported studies (which the original study very clearly was) allow for constructive discussion of alternative explanations. So, kudos all round.

Not least as that sequence team (correctly, imho) identified maze studies as good test cases.
Swings and roundabouts.

How “intelligent” is a slime mold? When it solves mazes, it might not be thinking:it’s obeying physics. Our new paper with
@jordiplam.bsky.social shows how it follows a least action principle,letting physics do the job arxiv.org/pdf/2511.08531
