Study Shows that 40,000 Years Ago Foxes Survived with Human Remains
Research by scientists at Tübingen University revealed that foxes survived more than 40,000 years of human waste. Where various sites in southern Germany were included in the study, it was noted that this species probably fed on the remains of animals large enough to be leftovers in human hunting hides.
Since the 1930s, foxes began to be ordered in major cities. In the future, London alone is making a home scroll for the red fox with a population of about 10 thousand. This city predators, and especially their finding shelter in remote areas far from the city center, and the currently available buffet trash, have become a common sight in many places.
It is especially important for these animals that the chicken tandoors thrown in the trash cannot escape and do not bite the foxes in the eyes. But now it turns out that in addition to the usual form of foxes, such as mice, field mice, rats, reindeer, and mammoths, they also feed on lightning human remains.
However, the challenge for researchers was finding evidence for this. If we want to see what modern foxes ate in the future, we could observe them, study what they ate, or look for food residue left in their droppings.
Before this time, the diet of foxes consisted of small animals.
But for older animals, this process is a little more complicated. Although it is possible to find fossilized animal excrement or to make inferences from tooth abrasions, it may take time to conduct extensive research to find direct markers.
If necessary for scientists at the University of Tübingen Senckenberg Center for Human Evolution and Paleoenvironment, some foxes were found in the form of fox bones excavated from several caves in the Swabian Jurassic, where some foxes were found anatomically in the Late Pleistocene between 42,000 and 32,000 years ago.
Before this time, the diet of arctic and red foxes consisted of small animals. However, looking at the isotopes recovered in later bones, a parallel change occurred, with modern humans being so numerous that they ruled out Neanderthals and affected new ecological niche foxes.
These are examinations of fox bones showing the proportions of isotopes with larger animals. Study author Hervé Bocherens,
“With the isotopic data in fox bones, we discovered that the nutritional structures of several animals changed. We now assume that these foxes are fed either directly by human hands or by the waste of meat left when we wander. “He said in the form.
According to the researchers, the meat belonged to the reindeer that people brought to caves to cut and cook or the mammoths that were difficult for the very big know and were slaughtered where they died from now on.
Unfortunately, this did not benefit the ‘foxes’. The jawbones found in the Lone valley Vogelherd cave showed us that the upper paleolithic cuts were used by humans as a source of foxes for meat and fur.
The research has been shared in PlosONE.
