Iberians c 25 ka: terrestrial diet

Marc Verhaegen
 


Stable isotope evidence of human diet in Mediterranean context during the Last Glacial Maximum
Dorothée G Drucker cs 2021 JHE 10.1016/j.jhevol.2021.102967

The Final Gravettian in Europe overlapped with the cold & dry event of Heinrich-2 c 27–23.5 ka, 
this caused the contraction of human distribution over refuge regions in the southern peninsulas of Europe.

Here we consider the human subsistence in NE.Iberia, where an extensive range of small to large prey was available. 
4 human remains from the Serinyą caves were investigated, using the stable isotope ratios of
-C, N & S of bulk collagen (d13Ccoll, d15Ncoll, d34Scoll) &
- phenylalanine & glutamine AAs (d15NPhe, d15NGlu).
Direct AMS-dating of the human & animal remains from the Final Gravettian levels of Mollet III, Reclau Viver & Arbreda at Serinyą confirmed
- their chronological position from 27.5 to 22.6 ka &
- the occurrence of 4 different human individuals.

The d13Ccoll & d15Ncoll values showed a large contribution of terrestrial prey to the dietary protein.
The d34Scoll values were consistent with a subsistence based on the local continental resources, without detectable contribution of marine resource.
The d15NPhe & d15NGlu values confirm that freshwater resources were not a substantial component of the diet of the considered individuals.
Contrast in the isotopic amounts in bulk collagen could be interpreted as the result of different proportions of terrestrial prey in human diet at Serinyą.

Altogether, the isotopic investigation reveals the importance of terrestrial over aquatic resources in the subsistence of the studied Final Gravettian individuals from the Serinyą caves in NE.Iberia during the LGMax.
It would be consistent with a scenario of a productive enough terrestrial eco-system to sustain hunter-gatherer subsistence in this refuge region.

Analysis of ancient bones reveals Stone Age diet details

31.3.21
Fish was not on the menu of the hunter-gatherers of southern Europe 27 ka.
Late-Gravettian Iberians mostly ate plants & land animals: rabbits, deer, horses. 
Drucker cs have been able to determine this for the first time on the basis of an isotope study of human fossils from the Serinyà caves in Catalonia.

In the Gravettian (33-25 ka), hunter-gatherers ate the food available in their local surroundings, e.g.
mammoth in C-Europe, horse & reindeer in Britain, seafood on the Atlantic or Mediterranean coasts of France & Italy.
During the LGMaximum 27-23 ka, the very cold & dry climate forced people to retreat to southern regions.
The Iberian, Italian & Greek peninsulas in particular were increasingly populated.

The fossil remains of 4 individuals from Serinyà (Spain) were not scientifically investigated for a long time, due to doubts about their age.
Researchers have now used radio-C-dating: the bones are 25-27 ka.
The very well-preserved bulk collagen from the bones made it possible  to carry out isotopic analyses,
this in turn makes it possible to determine what the people studied mostly ate.
For the first time, they combined this with a new method:
they separated individual AAs (amino acids) from the collagen, and analyzed their isotopic composition.
They say this has made it possible to trace in even greater detail whether the diet of Stone Age people was based on plant proteins, meat or fish & even which animal spp were consumed:
the 4 individuals from Serinyà had a diet based on terrestrial resources: plants & land animals from the region, esp. small animals such as rabbits.
The AA isotopes confirmed that the individuals ate almost no fish.
Until now it was assumed that people in this climatically harsh period were dependent on food from lakes, streams & the sea. 
Drucker points out that we are always learning more about the lifestyle and diet of Stone Age people:
"It appears that there was little fishing done in some populations in that era, even close to coastal regions.
Apparently, even in this cold climate, the terrestrial environment was productive enough to sustain people."

Gracile traits in dogs also spread by introgression from lap dogs in the Americas. Only these genes are classified by geneticists as of European origins. Which ends up with the Chihuahua according to Western genetics a European breed. When it is amply demonstrated the Chihuahua has always been a Mexican breed with the same morphology and temperament as ancient Mexican Chihuahuas. ____________________________________________________________________________________________When mistakes are repeated in different areas of genetics they lead to the same types of incorrect conclusions. Whether with humans or domestic dogs. European colonial cultural biases are at the root of these types of mistakes in genetics. ______________________________________________________________________________________________Of course some gracile traits arise independently. However, pygmies are long and well adapted to being gracile. Where dwarves are not, they are noveau. So pygmies are preadapted to being gracile where dwarves are just dwarfed big people and are not well adapted to being gracile. Thus whether in dogs or humans the bulk of genes related to being gracile come mostly from the first populations in the species to be gracile. _________________________________________________________________________________________________It is likely gracile genes in Native American dogs come from unknown gracile wolf populations (not entirely unknown). Pygmies, probably always have been gracile. With large bodies the derived condition in extant humans, and the pygmy condition being the primitive condition with an unbroken tradition of small bodied humans going back to the first Homo and before. ________________________________________________________________________________________________Other than the fragmentary archaic remains from the Congo, the best evidenced partly marine humans are archaic pygmies from Asia (Homo floresiensis and Palaua “pygmies” published by Berger et al). Very large feet in small bodied humans are not favorable for terrestrial or arboreal environments. _____________________________________________________________________________________________Though Homo floresiensis could run at low speeds well and climb well, they were making some trade off to be strong swimmers with those enormous feet. In Homo luzonensis trade offs were being made to be strong arboreal climbers, though the two populations were closely related they had different sets of derived traits unique to each group in the fossil record.

Not every person in most populations, and some entire populations today, are not gracile. In false linear evolution thinking natural selection acting upon traits or sets of traits, independently of the rest of the genome, is not taken into account. _______________________________________________________________________________________________Human evolution is not occasional Adams or super humans essentially replacing all other humans. It is a process in which each individual trait or groups of traits that work together are selected for or against. In modern evolutionary biology it is not at all a problem for gracile traits coming in by introgressions to be selected for and expand widely in a previously mostly robust humanity. ________________________________________________________________________________________________C Loring Brace understood this, however, it appears he did not explain it in a way others have been able to understand. He had many students and was popular, yet his work has never yet been mastered by any of his peers or students. __________________________________________________________________________________________________C Loring Brace correctly (by the late 1970’s) suggested that robustness in humans became selected against because of the use of more modern tools. For example he demonstrated that the over bite happened in different cultures at different times as a result of cutting food into small bites for infants (before that the incisors occluded in resting position, the first over bite is Mexico at 14kya where they had high quality obsidian knives). _____________________________________________________________________________________________Robustness has a very high cost. If that cost is no longer justified with the use of modern tools gracile traits can spread very quickly (without everyone becoming archaic or AMHS pygmies otherwise). As in a few tens of thousand of years. Brace did not make it clear whether he thought this was by convergent evolution in different groups or by spread of gracile genes. However, C Loring Brace certainly understand and expressed that gene flow between all human populations has been strong and steady all along (in keeping with Weidenreich 1948). _______________________________________________________________________________________________Different human populations have different appearances through natural selection, not through genetic isolation. They are tracking local conditions including that of their technology. There is always some level of continuity, people are more closely related to the first people where they live than distant people are. However, the bigger force is natural selection. Backwards ROoA thinking, which is inept in modern evolutionary biology and kinship relationships from anthropology, leads to all sorts of mistakes. _____________________________________________________________________________________________The ROoA marching conquering Roman armies model of human evolution is easier to teach and learn at first, but leads to obscene complexity as humn evolution is studied more deeply. This horrible whole picture complexity, with complex magical invocation, throwing out any contradictory evidence which can not be invoked away etc…, is why it has thus far been impossible for any ROoA paleoanthropologist to write a general paleoanthropology text book (too complex for them to do). Only multiregionalists, Wolpoff 1980 and myself 2020, have been able to write paleoanthropology text books. Yet for every multiregionalist in the West there are at least 20 ROoA.

AVA,

Newly derived would be a small subset of a larger population, most likely separated from the larger population.  We are talking about billions of people becoming more gracile.   It can only be self-domestication.

ROoA has it that the Sahulian element in Native Americans is via NE Asia (presumably by land through Beringia though there were certainly boats in Sahul within the last 50kya). Thus the Sahulian element was partly erased in North America by later Asiatic “migration” (gene flow through ordinary kinship relationships). Part of the ROoA dogma is that whenever possible, only “age of enlightment” Europeans has the ability to travel between continents. __________________________________________________________________________________________________Another possibility is intentional or waif travel directly from Sahul to the Americas very early. IMO Sahulian sealers living on the Greater Antarctica ice is the best explanation. During colder periods the sea ice (for people with small boats), was the most favorable place to live in the World. Seals were the greatest single mass of mammal flesh in the World, and there were marine plant and other marine resources. _________________________________________________________________________________________________People consider this impossible because Antarctica is so inhospitable now. However, the sea ice was much further out during cold periods, and in contact with much warmer water, with a much warmer climate than the Antarctic Coast today. _______________________________________________________________________________________________Relatively full blood Sahulians any place around NE Asia at any time is not evidenced either by the fossil record or genetics. Traces of Sahulian genes in early NE AMHS is due to gene flow out of Sahul such as post Toba. Not from some fantasy Sahulian population in the immediate area. However by invoking unevidenced essential replacements one can “prove” about any fantasy dogma in places and times for which there is little data. ______________________________________________________________Nor do ROoA paleoanthropologists know how to distinguish Sahulians from either Africans or Asians by fossils, so they are not in a position to know how poorly evidenced the hypothesis of Sahulians in NE Asia at any time is. Some how post WW II competency in understanding extant human systematics has become “racism”. Makes teaching and learning MUCH easier, but hardly leads to cogent understanding. ___________________________________________________________________________________________There even have been proposals from biological anthropologists that some how forensic anthropology should be banned (so that murderers can more easily get away with their crimes), because some how having the ability to know the geographic origins of humans remains is “racist”.  The Jomon clearly have some morphological affinities with Sahulians, but these are deep enough this is not detected in genetics for the most part (nor is the Jomon relationships with Europeans or other Asians detected yet in genetics).

Abstract

Different models have been proposed to elucidate the origins of the founding populations of America, along with the number of migratory waves and routes used by these first explorers. Settlements, both along the Pacific coast and on land, have been evidenced in genetic and archeological studies. However, the number of migratory waves and the origin of immigrants are still controversial topics. Here, we show the Australasian genetic signal is present in the Pacific coast region, indicating a more widespread signal distribution within South America and implicating an ancient contact between Pacific and Amazonian dwellers. We demonstrate that the Australasian population contribution was introduced in South America through the Pacific coastal route before the formation of the Amazonian branch, likely in the ancient coastal Pacific/Amazonian population. In addition, we detected a significant amount of interpopulation and intrapopulation variation in this genetic signal in South America. This study elucidates the genetic relationships of different ancestral components in the initial settlement of South America and proposes that the migratory route used by migrants who carried the Australasian ancestry led to the absence of this signal in the populations of Central and North America.

Turned Head Test.

That makes sense. When neurotypical people are shown a face, head on, if you track their eye movements they stare at the eyes, almost the whole time, as if mesmerised.

Schizophrenics and autistic people's eyes look at the whole face, referring back to the eyes occasionally but also looking at the background, reading the titles of books on the bookshelf, etc. No wonder they are able to recognise the face better. They were the ones who actually looked at it in the first place.

I found a book on my mother's bookshelves with the memorable title -- "Schizophrenia." That's where I read those other factoids.

Another one is that schizophrenics pee orange,  because of a red chemical in their urine called haematochrome, which induces hallucinations in neurotypical people.

A friend of mine shared a house in Swansea with some quite druggy housemates and one schizophrenic, whom they found one morning peeing in the stew "to give the others a treat."  😊😊

I was talking to a schizophrenic who had coordinated and chaired a nationwide conference on mental health in the UK (I was there representing Bath MIND). He told me some of his experiences and, rather mischievously, I asked him if he would like to be cured of his schizophrenia. He just laughed and told me how flat and meaningless his mundane day-to-day life had seemed before his "illness" in comparison with the amazing things he had seen and done in the 5 or 6 years since. 

I gave a lecture on it once, suggesting it might better be considered an evolutionary advance than an illness. The one schizophrenic who attended certainly felt that way. "Colours are brighter. I think faster and more vividly.  I feel more alive than I ever used to."

The book gave examples of how the actions of a person with heightened sensibilities can appear quite insane to neurotypicals, while being perfectly rational once you know the reasoning. Often, they are working on the basis of factors that no one else even notices, and this can lead to a lot of misunderstandings with neurotypicals.

If you want to know more, maybe email me at garethmorgan@..., because we're getting a bit off-topic for AAT.

Then, one shows the test subject 10 photographs on the same page, again just showing facial features with the hair removed but the faces turned 45 degrees and asks the test subject to pick out the same person where the test subject saw the photo of the person looking straight into the camera. 

It has been a long time since I read that study. I know the people with schizophrenia did better. I think I remember that their speed was quicker in picking out the correct photograph from the 45 degree head turned photos. The study might have been limited to persons with paranoid schizophrenia. I read it so long ago, I forget who did the study and where it was published. It was significant in that in all cognitive tests, persons with schizophrenia usually do worse than people without schizophrenia. I also had the standardized test with all the photographs in a spiral notebook.

Abstract

Different models have been proposed to elucidate the origins of the founding populations of America, along with the number of migratory waves and routes used by these first explorers. Settlements, both along the Pacific coast and on land, have been evidenced in genetic and archeological studies. However, the number of migratory waves and the origin of immigrants are still controversial topics. Here, we show the Australasian genetic signal is present in the Pacific coast region, indicating a more widespread signal distribution within South America and implicating an ancient contact between Pacific and Amazonian dwellers. We demonstrate that the Australasian population contribution was introduced in South America through the Pacific coastal route before the formation of the Amazonian branch, likely in the ancient coastal Pacific/Amazonian population. In addition, we detected a significant amount of interpopulation and intrapopulation variation in this genetic signal in South America. This study elucidates the genetic relationships of different ancestral components in the initial settlement of South America and proposes that the migratory route used by migrants who carried the Australasian ancestry led to the absence of this signal in the populations of Central and North America.

AVA,
Newly derived would be a small subset of a larger population, most likely separated from the larger population.  We are talking about billions of people becoming more gracile.   It can only be self-domestication.

IMHO.  Hairlessness is a recent phenomenon due to domestication, but the e streamlined hair pattern, fat layer and loss of underfur are ancient swimming adaptation.

Re: Parsimony is popular among geneticists, unpopular among paleoanthropologists

Fao Allan

A robust and vigorous defence. Excellent!



Nobody minds parsimony. We are usually accused of being too fond of parsimony.


in the hope that they will help test it.

How? Which bit is testable?


Oil geologists would have no interest or knowledge of the volcanic rocks on Bioko,

Bioko is a major oil producer. Oil deposits are often intimately related to volcanic activity. The Zafiro field has over a hundred oil wells and reserves of over a billion barrels. I think the Mobil geologists would know the area quite well. They might know, for instance what parts of the island, if any, are not buried under volcanic rock.



The volcanic rocks that are exposed on the coast of Bioko are less than 1.3 million years old.

Last week you said that aboriginal H. sapiens were living there all along, the last ones leaving 55,000 years ago. You previously said the we split from other apes sometime between 20 million and 5 million years ago, if I remember correctly. I don't think I've managed to grasp the finer point here.

Wikipedia says that the volcanoes are from the Holocene and still active, so is there any evidence at all that there was anything there more than 10,000 years ago?

Bioko has a vast range of endemic species from monitor lizards to lots of different primates. Is there a reason you think hominins became extinct there?



That same lack of evidence applies also to the coasts of the Mediterranean, Tethys, East Africa, India, Southeast Asia, Indonesia, and China

No it doesn't. There are lots of fossils and shells and stone tools in all those places.




What million-year-old shell middens can you point to?

Trinil at 500,000.  Olduvai Gorge, bed III, at (800,000 to 1.15 million years old) https://www.researchgate.net/publication/305182169_Paleoecologic_significance_of_malacofauna_Olduvai_Gorge_Tanzania



I did not "tamper with" the chart.

Fair enough, but when you said "Here is a paper that I just came across yesterday. " and pasted an image from it with the same URL, some people might think that was a bit misleading.



0.000000001 mutations per base pair per year.

Tells us nothing then.

Homo erectus at Trinil on Java used shells for tool production and engraving
Josephine Joordens ... Stephen Munro ... 2015
Nature 518:228-231 doi 10.1038/nature13962

The manufacture of geometric engravings is generally interpreted as indicative of modern cognition & behaviour,
but is this innovation restricted to H.sapiens?
and has it a uniquely African origin?

Here we report on a fossil freshwater shell assemblage from the Hauptknochenschicht (Trinil, H.erectus type locality), discovered by Eugène Dubois in 1891.
In the Dubois collection (Naturalis museum, Leiden, NL) we found evidence for
- freshwater shellfish consumption by hominins,
- 1 unambiguous shell tool &
- 1 shell with a geometric engraving.

We dated sediment contained in the shells with 40/39Ar & luminescence dating methods,
we obtained
- a max.age of 0.54 Ma ± 0.10,
- a min.age of 0.43 Ma ± 0.05:
the Hauptknochenschicht (HKS) is younger than previously estimated.

Our data indicate:
- the engraving was made by H.erectus,
- it is considerably older than the oldest geometric engravings described so far.

At present it is not possible to assess the function or meaning of the engraved shell,
but this discovery suggests:
engraving abstract patterns was in the realm of Asian H.erectus cognition & neuro-motor control.
