Bsky is growing - follower lists do, too.

Let me introduce myself.

I study archaeology, biology & psychology. The common theme: evolution of cultural evolution (especially of: tools).

Two recent interviews give an overview:

Our cultural backgrounds almost always (perhaps unavoidably) influence our epistemology & the questions we ask. Especially in the human sciences. E.g. some really interesting discussion here about how renascence values shape our thinking about neanderthal artwork.

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.

Most researchers are unaware that the concerns about strength of theories, methodology, and lack of generalizability led to a crisis in the 60's and 70's as well. Nothing changed then, and history is a good teacher for why nothing is likely to change this time around doi.org/10.5334/irsp...

Naive humans can reinvent knapping techniques - but can they also reinvent strategies to make early handaxe shapes?

Turns out, yes, they can!

Check out Nolan's new study (open access) and I recommend to follow him, too. He is going places.

So TL;DR, it costs us 1.5 cents per 3D printed whistle (approximately) in filament and electric costs, compared to about 6 for drop shipping; we're more nimble with a distributed network, and also, they can't just seize our whistles off the ship and stop the whole thing; and we pay less in shipping.

Italian voice actor Carlo Bononi was the voice of all of the characters on Pingu. A trained clown by trade, he used a theater technique called grammelot, which consists of "speaking" in a mix of babbled gibberish noises. He improvised all the voices live and unscripted.

This is part of a thread on a paper in a predatory journal. But this absolutely happens in non-predatory journals, too. I have noticed *several* examples already.

Here's the reality this example illustrates:

It's not even just about people blindly trusting what ChatGPT tells them. LLMs are poisoning the entire information ecosystem. You can't even necessarily trust that the citations in a published paper are real (or a search engine's descriptions of them).

One of the undergrads in my lab cited a paper in their Honours thesis that doesn't exist. I am guessing they are trying to use AI to "help" with their lit review and didn't bother trying to download the actual paper.

Thanks tech-bros for making academia worse.

Just saw this in my inbox. It seems to make a claim for biologically predisposed (due to natural selection) anatomy for nutcracking using hammers with power grips in west African chimpanzees.

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.

I had not seen this before. Very interesting, by Jane Goodall - taken from the transcipt of this interview: freakonomics.com/podcast/jane...
"LEVITT: I think it’s fair to say that the most impactful single insight from your early work is that the chimps in the wild use tools. They make tools. They take objects and intentionally alter those objects to make them better at accomplishing a task. Like stripping away at blades of grass until they’re just right for dipping into the anthills. And before you observed that, there was a thought that humans were the only species that made these tools. To you personally, is that the most notable insight? GOODALL: When I started in 1960, nobody had studied chimps in the wild. No scientist, that is. If, at that time you had gone into some of the indigenous people living deep in the rainforest, they would’ve told you chimpanzees used to make tools. They knew it. But, of course, now we are back on the scientific bandwagon. So when I saw David Greybeard using and making tools, I knew it was really exciting. It was what enabled Leakey to go to the Geographic to get funding when my six months of money ran out. But there’s a wonderful book written by a psychologist, called The Mentality of Apes, Wolfgang Köhler, and he studied this colony of captive apes, and he described so many innovative use of objects. But at that time, the scientific community said, “Oh, well, these were chimpanzees in captivity. Therefore, our human characteristics had rubbed off onto them. It’s nothing to do with what they, as wild individuals, would be capable of.” So when I observed that momentous day of David using and making tools, I knew that it was going to make a big impression on the science of the time. But I wasn’t surprised because I, unlike the other scientists, had believed that what Köhler was reporting was the ability of chimpanzees to use and make tools."

Orangutan youngsters reach the broad diet they need to survive only if they culturally learn what to eat & where to find it

-> This is the first clear evidence for cultural dependency of any kind in apes <-
