A group of scientists discovered that diet of the neanderthals Siberians included plants and animals, according to international research leading the University of the Spanish city of Valencia (UV). The experts, both from Spain, What Germany, Canada, Holland Y Russia, documented this feeding through a combination of stable isotope analysis and identification of plant micro-remnants of an individual.
The international research team took bone samples Y dental stones of Neanderthal remains, which were dated between 60 thousand and 50 thousand years of the deposit of Chagyrskaya, in the Altai Mountains in southern Siberia, just 100 kilometers from the cave Denisova.
This region is considered “very dynamic”, since there the Neanderthals also interacted with their Asian cousins, the denisovanos.
The work was carried out both based on Western Siberia, where there are studies that explain that the modern humans responded with high mobility, as in oriental, where jobs are missing to analyze the behavior and subsistence of Neanderthals, who inhabited this Siberian forest steppe, which is more arid and colder than the western one.
The species occupied western Eurasia before disappearing and, although it was estimated that it extended to what is today Uzbekistan, in recent years it was discovered that 2 thousand kilometers further east to the Altai Mountains in Siberia.
Analysis of the stable carbon and nitrogen isotopes of a jaw, meanwhile, revealed that this individual had a relatively high trophic level compared to the local food web. This indicates that they consumed a large amount of animal protein hunting large and medium-sized animals.
The researchers identified, using light microscopy, a set of plant particles preserved in the dental calculus of the same individual, as well as others from the site.
Plant micro-remnants indicated that the species also consumed several plants different.
The region was tempting enough for Neanderthals to colonize the area at least twice, but genetic data indicates that they barely held on and they lived only in small groups that were constantly in Danger of Extinction.
Domingo Carlos Salazar, who coordinated the research explained: “Even in adverse climatic environments, Neanderthals were capable of having a varied diet. It was really surprising that these eastern Neanderthals had very similar subsistence patterns to western Eurasia. “
