I find things like that hard to perfectly square with observations like the Flynn Effect (“the substantial and long-sustained increase in both fluid and crystallized intelligence test scores that were measured in many parts of the world over the 20th century”): https://en.wikipedia.org/wiki/Flynn_effect
Why? Draw the line backwards, and in a couple of decades you are down at 0 IQ. That's clearly absurd, you can't draw any conclusions of IQ significantly before 1950 from how the line behaves after 1950.
For any given IQ test, the norming sample is taken once. So if everyone gets twice as smart as before, everyone's IQ, as measured by any existing IQ test, would go up.
Look up the Flynn effect ... it refers to an actual change in performance.
That the scores on a given IQ test are occasionally renormalized so that the mean is 100 has no bearing on whether "IQ is a statistical distribution", whether intelligence or whatever the heck IQ measures can be measured absolutely, or on the validity and meaning of the previous statements by Epa095, sokoloff, and irdc and why they are or are not true.
If everyone suddenly gets twice as smart as before, all of their IQs will shoot up until the scoring of every IQ test is renormalized to a mean of 100.
I find it interesting that you are basically saying the same thing, even if the reply you are confused by simply made some assumptions you were not able to make and was a bit less precise.
It’s interesting how people will say things like “This is wrong and confused in every possible way” even though it’s not, making it and them in turn the ones “wrong and confused in every possible way”.
Maybe if we are a bit more generous with others we won’t be compelled to be so pretentious and denigrating by saying things like “This is wrong and confused in every possible way”, about something someone said and believes.
The Flynn effect has its own little nurture vs nature debate within it.
Was it better medicine and food that stopped both your height and your brain from being stunted?
Or was it people being trained from birth for a world where doing abstract brain teaser tests was important.
Notably both cause problems for the typical racist's use of IQs. If you can improve the scores with such interventions it makes a lot of their genocidal policy recommendations seem less scientifically sound, so they put a lot of effort into denying that IQ scores can be improved by interventions. Even though they have been, for decades.
It seems obvious that IQ test scores can be improved with interventions and further that actual [as opposed to measured] general intelligence can be affected by environmental factors that shape whether the brain develops under good, neutral, or damaging conditions (nutrition, sleep, language usage, stress, etc.).
With all the energy that's been spent on the topic, I'm slightly surprised that this isn't entirely settled by now and any opposing view being relegated to fringe/flat-earth territory.
Are you suggesting our brains are getting better? I find it far more likely that our improved education techniques and our skyrocketing access to information as being the cause.
If the measured cognitive abilities of a typical 2000-era Homo sapiens are statistically significantly different from 1900-era Homo sapiens, to me that casts some doubt as to how likely similar a 125K years ago and since out-competed species was.
Was the era from 1900 to 2000 so special/different as to be a one-off?
(This is obviously an unpopular line of inquiry/source of confusion based on the voting.)
Firstly, this is completely orthogonal. But it's also improper reasoning.
If Neanderthal had bigger brains (they did) or had different cognitive abilities, there's a chance they were baseline smarter than homo sapiens at the time.
Being perhaps a little smarter doesn't mean you win the evolutionary game. There are so many factors at play.
> average Neanderthal cranial capacity for females was 1300 cm3 and 1600 cm3 for males. [Modern humans, 1473 cm3.]
Nor the dude Neanderthals, since they were using the swollen brainparts for vision and coordination:
> Neanderthals had larger eyes and bodies relative to their height [...] when these areas were adjusted to match anatomically modern human proportions it was found Neanderthals had brains 15-22% smaller than in anatomically-modern humans.
Edit since I don't even agree with the concept: even if the extra capacity was differently distributed such that they had more ... powerful? ... executive functions, what's smartness? More imagination, OK, more self-restraint, more planning. More navel-gazing, more doubt, more ennui.
Or it could be more communication, often proposed as what gave sapiens the edge. Chattering bipeds. It's an association between the brain doing something and the species proliferating, that's what we're calling smart, but doing what? It could just mean our ancestors were compulsively busy. Same thing as smart, perhaps.
We will never get that the cranial volume is not the same as inteligence/brain function, or whatever you might call it. Reminder that Einstein brain was smaller than average, and female brain are smaller than male. Phrenology will haunt us forever, in one form or another.
Most likely, some Neanderthals were asimilated into modern humans, most were exterminated in tribal clashes. Reminder also that our almighty specie was almost wiped out from history around 800,000 years ago (https://www.science.org/doi/10.1126/science.abq7487), being the most intelligent organism ever existed.
I don't think that matches archeological findings. From what I understand the reason neanderthals are understood to have been less intelligent than sapiens is because neanderthal tools found are cruder than sapien tools from around the same periods and areas.
> Being perhaps a little smarter doesn't mean you win the evolutionary game. There are so many factors at play.
Considering most human groups have a % of Neanderthal DNA, they didn't exactly lose... Based on the % of Neanderthal vs. Sapien DNA, it seems Neanderthals were simply outnumbered.
Are numbers everything? Are sardines more evolved than whales?
Anyhow, the traditional view is that Neanderthals were brutes who were actually out-competed and killed off by Sapiens. The more realistic view considering the evidence is that Neanderthals were much closer to Sapiens, equally or even more sophisticated, but less numerous, and thus their contribution to our DNA is smaller than Sapiens.
But do keep in mind the Neanderthals live on because Europeans and Asians are all part Neanderthal.
I think especially given TFA and our inferred history with them that they were terrifying apex predators who occasionally raped human women.
I don’t much believe the friendly smiling museum depictions that have lately become fashionable. Their eyes alone would have made them something you didn’t want to run into at night.
Are there any good illustrations showing how much bigger their eyes were compared to modern humans? Is it really significant? I'm having trouble finding anything that makes it clear.
And lets not forget that all hominins fight amongst themselves, rape each other, etc... The assumption that Neanderthals were particularly brutish is just that, an assumption.
> According to Svante Pääbo, it is not clear that modern humans were socially dominant over Neanderthals, which may explain why the interbreeding occurred primarily between Neanderthal males and modern human females.
Unless read as suggesting "Neanderthal males were hugely charismatic"?
Neah, can't be. We are meticulously excluding fat from our diet. Fat-free milk, fat-free yogurt, fat-free brain. I bet they had better cognitive abilities for they understood the importance of fat better than we do apparently.
It’s convenient to buy fat-free products to lower caloric density of everyday food. Given mostly sedentary lifestyle, maintaining healthy caloric intake is pretty hard, and limiting fats (not only fat-free dairy, but also lean meats) and sugars really helps. Note limiting, not excluding — going extreme fat-free is definitely bad for health, and it also takes huge effort compared to just limiting.
I'm in Alberta (Canada), and I just saw some in the grocery store last week. I actually can't recall ever seeing a store without 3.25% milk here. It's usually called "homo(genized) milk" rather than "whole milk", but those two phrases both mean the exact same thing.
Interesting, US grocery stores never stopped carrying whole milk. It was readily available amidst the 90s fat panic. It’s what my family always bought.
Probably the difference is that extracting as many calories as possible from food was a guarantor of survival for the neanderthals whereas that's not so true with the level of calorie abundance we have in the western world, partly because of analogous fat refining processes we also use.
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 answer that seems to be emerging from several different lines of research is that a) they always had fairly low fertility and b) they didn't really go extinct as such, they just intermixed with Homo Sapiens Sapiens and because the later had much higher fertility, Neanderthal genes got diluted down to the present ~2% in the Eurasian population.
Sounds plausible indeed. Anyways, neanderthals operating a large scale fat production 125 thousand years ago could be a good plot for another hollywood movie scenario. Any takers?
Doesn't outcompete include murder? We are a very tribal species, and the history is full of genocides and mass murders, so from a very uneducated viewpoint, this sounds reasonable.
If not that, is it that we depleted the resources they depended on?
Great question. When people say outcompete it can certainly include violence but we’re talking about populations spread over continents over thousands of years. Factors like technology, fertility, adaptability, etc. are more what people mean when they said outcompete.
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!
> At this location, researchers found that Neanderthals not only broke bones to extract marrow but also crushed large mammal bones into tens of thousands of fragments to render calorie-rich bone grease through heating them in water.
AFAIK Neanderthals didn't have clay pots - how would they hold the water to heat it and put the bone pieces in?
EDIT: I asked claude and it doesn't know for sure but guessed "stone boiling into an organic container — animal stomach, hide, or a bark vessel — remains the most plausible explanation for how they heated the water."
One point here is that you can boil water over a fire in a flammable container.
Here, this isn't about boiling, but similar: "Because the Neanderthals had no pots, we presume that they soaked their seeds in a fold of an animal skin," says Chris Hunt, a genuine (checks) expert in cultural paleoecology.
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.)
you are my hero; and this is why i love hn, cause this was something in the back of my mind that i wanted to find out about, and what do you know, a fellow hn'er just wrote it in a random comment. thanks!!
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
Based on 20g rdv, they could be estimating ~40kg of rendered fat for 2000 servings. I can't tell from the wording whether they don't know the population and are implying that's a possible maximum or are just trying to relay the observed production capacity.
Look into pre-Colombian grease trails, which we have much better logistical records for.
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.
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).
"rabbit starvation" refers to a diet of mostly lean protein, deficient in fat. So much so that it results in malnutrition.
Eating nothing but rabbits is one way to get it, but is not really about "subsisting on small herbivores". It's the fact that the meat is very lean, not fatty. Apparently "mal de caribou" is the same thing, and Caribou / Reindeer are not small.
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?
> 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.
Yeah like the rhinos and elephants that I didn't know you used to get in that area. Maybe they were too efficient and that's what limited their proliferation when they hit resource limits?
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.
They’re still meaty and they aren’t taboo everywhere!
Whenever I go to the family farm I check to see if there are any fat juicy grilled rats at the local market. Alas, I’m still too squeamish to eat them, but I’m working up to it!
>De Rat (English: The Rat) is a smock mill in IJlst, Friesland, Netherlands, which was originally built in the seventeenth century at Zaanstreek, North Holland. In 1828 it was moved to IJlst, where it worked using wind power until 1920 and then by electric motor until 1950. The mill was bought by the town of IJlst in 1956 and restored in the mid-1960s. Further restoration in the mid-1970s returned the mill to full working order. De Rat is working for trade and is used as a training mill. The mill is listed as a Rijksmonument (No. 39880).[1]

I assume you're seeing the text starting with "The authors emphasise the sheer quantity of herbivores"? I see that too in reader mode, both on my iPhone and Mac.
The text is in the article, second paragraph under "survival strategies". I don't see any obvious reason in the HTML why reader mode is skipping everything else.
