Alimentation de Néandertal

Pour l’alimentation des autres hominines, voir la page [données scientifiques]

Globalement, les recherches récentes confirment l’image de Néandertaliens consommateurs de très grands animaux, mais aussi d’une importante diversité de plantes (ces deux consommations étaient remarquablement anticipées par Jean Auel dans Les enfants de la terre, dès 1980). La question de la part glucidique dans l’alimentation de Néandertal reste un sujet de débat (de même que chez Homo sapiens au paléolithique).

Reconstructing Neanderthal diet: The case for carbohydrates [Texte] [PDF]
Hardy et al.
Journal of human evolution, 2022

Today, nutritional guidelines recommend that around half the diet
should be carbohydrate, while low intake is considered to compromise physical performance and successful reproduction. This is likely to have been the same for Paleolithic populations, highlighting an anomaly in that the basic physiological recommendations do not match the extensive archaeological
evidence. Neanderthals had large, energy-expensive brains and led physically active lifestyles, suggesting that for optimal health they would have required high amounts of carbohydrates. […]
We end by proposing that analyses of Paleolithic diet and subsistence strategies need to be grounded in the minimum recommendations throughout the life course and that this provides a context for interpretation of the archaeological evidence from the behavioral and environmental perspectives.

Dietary evidence from Central Asian Neanderthals: A combined isotope and plant microremains approach at Chagyrskaya Cave (Altai, Russia) [Texte]
Salazar-Garcia et al.
Journal of human evolution, 2021

Stable isotopes identify one individual as possessing a high trophic level due to the hunting of large- and medium-sized ungulates, while the analysis of dental calculus also indicates the presence of plants in the diet of this individual and others from the site. These findings indicate eastern Neanderthals may have had broadly similar subsistence patterns to those elsewhere in their range.

The exploitation of rabbits for food and pelts by last interglacial Neandertals [PDF]
Pelletier et al.
Quaternary science reviews, 2019

The high frequency of rabbits in the Pié Lombard Mousterian assemblage, comprising at least 225 individuals, is unique for this period and probably reflects the location and function of the rock-shelter. The capture of such a hight number of this small mammal potentially required sophisticated acquisition techniques formerly known only from Upper Palaeolithic contexts.

New evidence of broader diets for archaic Homo populations in the northwestern Mediterranean [PDF]
Morin et al.
Science advances, 2019

Investigating diet breadth is critical for understanding how archaic Homo populations, including Neanderthals, competed for seasonally scarce resources. The current consensus in Western Europe is that ungulates formed the bulk of the human diet during the Lower and Middle Paleolithic, while small fast prey taxa were virtually ignored. Here, we present a multisite taphonomic study of leporid assemblages from Southern France that supports frequent exploitation of small fast game during marine isotope stages 11 to 3. Along with recent evidence from Iberia, our results indicate that the consumption of small fast game was more common prior to the Upper Paleolithic than previously thought and that archaic hominins from the northwestern Mediterranean had broader diets than those from adjacent regions. Although likely of secondary importance relative to ungulates, the frequent exploitation of leporids documented here implies that human diet breadths were substantially more variable within Europe than assumed by current evolutionary models.

Stable isotopes reveal patterns of diet and mobility in the last Neandertals and first modern humans in Europe [Texte]
Wibing et al.
Nature Scientific Reports, 2019

For both UPMH individuals, the two most relevant prey species are the mammoth and the reindeer. Each species comprised roughly 25–30% of the meat protein source. The rhinoceros contributed ca. 15 to 20%, the bovines and horses around 10% of the dietary proteins. Cave bears played the least important role, with a maximum contribution of around 5% of the total protein intake. These results are similar to those of Neandertals, which indicates that both UPMHs and Neandertals had a similar prey choice with preference for mammoth and reindeer.
[…] The zooarchaeological records from Goyet and Spy fully support mammoth hunting episodes with a special preference for younger individuals and possibly their mothers. Interestingly, based on stable isotopes, the mammoth seems to contribute the major part of the dietary protein of humans in a time range between 50,000 and 30,000 years ago and across wide areas spanning from SW France to the Crimean Peninsula

“Neanderthals, vitamin C, and scurvy” [Texte]
John D. Speth.
Quaternary International, 2018

As a consequence, common methods of preparing meat for storage and consumption (e.g., drying, roasting, boiling) may lead to significant loss of vitamin C. There are two effective methods of minimizing such loss: (1) eating meat raw (fresh or frozen); and (2) eating the meat after it has been putrefied. Putrefaction has distinct advantages that make it a common, if not essential, way of preparing and preserving meat among northern latitude foragers and, for the same reasons, very likely also among Paleolithic foragers in the colder climes of Pleistocene Eurasia. Putrefaction “pre-digests” the meat (including the organs), making it much less costly to ingest and metabolize than raw meat; and it lowers the pH, greatly increasing the stability of vitamin C. These observations offer insights into critical nutritional constraints that likely had to be addressed by Neanderthals and later hominins in any context where their diet was heavily meat-based for a substantial part of the year.

Neanderthal behaviour, diet, and disease inferred from ancient DNA in dental calculus (p) [PDF]
Weyrich et al.
Nature, 2017

At Spy cave, Belgium, Neanderthal diet was heavily meat based and included woolly rhinoceros and wild sheep (mouflon), characteristic of a steppe environment. In contrast, no meat was detected in the diet of Neanderthals from El Sidrón cave, Spain, and dietary components of mushrooms, pine nuts, and moss reflected forest gathering2,3. Differences in diet were also linked to an overall shift in the oral bacterial community (microbiota) and suggested that meat consumption contributed to substantial variation within Neanderthal microbiota. Evidence for self-medication was detected in an El Sidrón Neanderthal with a dental abscess4 and a chronic gastrointestinal pathogen (Enterocytozoon bieneusi).

Neandertal versus Modern Human Dietary Responses to Climatic Fluctuation [Texte]
Sireen El Zaatari et al.
PLOS One, 2016

Specifically, whereas the Neandertals altered their diets in response to changing paleoecological conditions, the diets of Upper Paleolithic humans seem to have been less affected by slight changes in vegetation/climatic conditions but were linked to changes in their technological complexes. The results of this study also indicate differences in resource exploitation strategies between these two hominin groups. We argue that these differences in subsistence strategies, if they had already been established at the time of the first contact between these two hominin taxa, may have given modern humans an advantage over the Neandertals, and may have contributed to the persistence of our species despite habitat-related changes in food availabilities associated with climate fluctuations.

The Neandertal meal : a new perspective using faecal biomarkers [Texte]
Sistiaga et al.
PLOS One, 2014

Analysis of five sediment samples from different occupation floors suggests thatNeanderthals predominantly consumed meat, as indicated by high coprostanol proportions, but also had significant plantintake, as shown by the presence of 5b-stigmastanol. This study highlights the applicability of the biomarker approach inPleistocene contexts as a provider of direct palaeodietary information and supports the opportunity for further research intocholesterol metabolism throughout human evolution.

Plant foods and the dietary ecology of Neanderthals and early modern [Texte]
Henry et al.
Journal of human evolution, 2014

Our results suggest that both species consumed a similarly wide array of plant foods, including foods that are often considered low-ranked, like underground storage organs and grass seeds. Plants were consumed across the entire range of individuals and sites we
examined, and none of the expected predictors of variation (species, geographic region, or associated stone tool technology) had a strong influence on the number of plant species consumed. Our data suggest that Neanderthal dietary ecology was more complex than previously thought. This implies that the relationship between Neanderthal technology, social behavior, and food acquisition strategies must be better explored.

To meat or not to meat? New perspectives on Neanderthal ecology [Texte]
Fiorenza et al.
American journal of physical anthropology

Neanderthals have been commonly depicted as top predators who met their nutritional needs by focusing entirely on meat. This information mostly derives from faunal assemblage analyses and stable isotope studies: methods that tend to underestimate plant consumption and overestimate the intake of animal proteins. Several studies in fact demonstrate that there is a physiological limit to the amount of animal proteins that can be consumed: exceeding these values causes protein toxicity that can be particularly dangerous to pregnant women and newborns. Consequently, to avoid food poisoning from meat‐based diets, Neanderthals must have incorporated alternative food sources in their daily diets, including plant materials as well.

We conclude that described use of shellfish resources by Neanderthals (H. neanderthalensis) in Southern Spain started ∼150 ka and were almost contemporaneous to Pinnacle Point (South Africa), when shellfishing is first documented in archaic modern humans.

Human consumption of tortoises at Level IV of Bolomor Cave (Valencia, Spain) [Texte]
Ruth Blasco, 2008

Level IV of Bolomor Cave has provided sufficient evidence to show proof of human consumption of tortoises in Later Middle Pleistocene. The use of tortoises for food appears to be quite common among the hominids that occupied the cave at Level IV. Although some exceptions do exist, these human groups follow specific patterns to process the tortoises. These patterns have been observed in the systematic use of fire to consume the nutrients from these animals. Thus, the consumption sequence of these small prey starts with them being cooked. Habitually, the tortoises are placed into the fire upside down and are roasted in its shell.
