This pairs nicely with the recent publications around Neanderthal cognitive abilities and how there likely similar to ours (https://arstechnica.com/science/2026/04/neanderthal-brains-m...).

Fascinating. Considering the industrial scale fat production that the neanderthals managed to operate according to this article, it makes me wonder even more whether we still understand why exactly they went extinct in 80 thousand years later.

The article mentions "rendering fat (from bones)" many times, but doesn't say how neanderthals actually did it? My best guess is they broke the bones into many little pieces, threw them in a fire, and waited for the fire to extinguish and cool, thus producing hardened (rendered) fat.

Feels like the most interesting part of the article was omitted!

Here's something random about "Neanderthal".

The word comes from the Neander Valley (Neander-thal) where their fossils were originally discovered. It was named after Joachim Neander, a 17th-century German pastor. Neander is a latinization of his family name Neumann, meaning "new man".

So not only did we discover a new type of man in a valley named new man, but the computers that are used for artificial intelligence (a future type of new man) all use the von Neumann architecture.

I found that amusing.

(Other random detail: The word "dollar" is derived from "thal". The Holy Roman Empire first minted standardized 1 ounce coins made out of silver from mines in Joachimsthal ("Joachim's Valley") and so were called Joachimsthalers. That got shortened to "thaler", then through Low German "daler" then Dutch to English.)

Do we know how many people were in the community? Maybe I missed it in the article? 2000 people worth it food a day is hard to put into perspective otherwise. Though it's all very impressive regardless

Reminds me of the Barbegal mills, built in ancient Rome. The site produced 4.5 tons of flour per day, according to wikipedia. https://en.wikipedia.org/wiki/Barbegal_aqueduct_and_mills

There is evidence for neanderthals making gum/glue from birch bark. It's useful for hating stone onto wood for tool making.

I wonder if this bone grease was an edible product or something else. Oils have many uses.

Planning ahead, bulk processing, storing for later. Sounds less like primitive survival and more like logistics. Every time we dig deeper the gap between them and us gets smaller.

And that's how Toyota eventually got to lean manufacturing, impressive!

That also must mean that Neanderthals must have been very clever, early on. We already knew they were clever, but 125.000 years ago is really pushing that further. Now the main question is still why and how they went extinct. We have some pieces of the puzzles (mitochondrial DNA found in human mitochondrial DNA) but not a complete picture yet (or, somewhat more complete; we can obviously never reconstruct all pieces of the puzzle).

I am fat so?

Question: why do we know this was about food? Bones are boiled for other reasons. Boiling down bones is how you make basic glue. Could this have been something more industrial, the creation of a useful ingredient for weapon making?

I like the explanation of Neil Tyson on Neanderthal's research.

university of leiden is a great institution and i am blessed for having studied there despite dropping out!

Some would argue they still do. ;)

Pretty clever solution to rabbit starvation.

Maybe when megafauna disappeared, so too the Neanderthals because their survival strategy was too dependent on them.

> the tip of the proverbial ice-berg of Neanderthal impact on herbivore populations, especially on slowly-reproducing taxa, could have been substantial during the Last Interglacial.’

translation: the Neanderthals probably completely wiped out a ton of the species of big animals that once existed in these regions.

Homo sapiens isn’t the only hominid to do that…

“Be he alive or be he dead, I’ll grind his bones to make my bread.”

I read this as 'RAT factories' - like Neanderthal decided to breed thousands of rats presumably for food. Assuming rats were meaty and not taboo then, as they are now.
