Research results showing that Neanderthal's diet and kissing from dental plaque

ByErich Ferdinand

In the cave called Sidrón Cave in Spain, I know that the Neanderthal people lived 50,000 years ago, but a study was conducted to analyze the dental plaque remaining on the discovered Neanderthal's teeth I know that the Neanderthals of the Nanderthar people were living a harsh life of eating mushrooms, mosses, pine nuts, etc., eating molds to treat the disease, probably kissing.

The study of analyzing Neanderthal's dental plaque was conducted by Alan Cooper of Adelaide University and Keith Dovney of Liverpool University. The research team conducted the first attempt to analyze the DNA sequence of the Neanderthal calcified plaque discovered more than 20 years ago. Although pollution covering dental plaque of 50,000 years ago made it difficult to identify ancient microorganisms and foods, due to the improvement of the technique to analyze ancient DNA, from the Neanderthal diet of those days, I was able to predict until I was kissing.

The research team compared a group of Neanderthal people who lived in Sidrón Cave, Spain, and a group living in Spy Cave in Belgium. Both groups were eating mushrooms, while the Spy Cave group had eaten a kind of fur covered rhinoceros and sheep, while the group of Sidrón Cave planted plants and was eating it The difference in diet is known. In addition, the group of Sidrón Cave knows that they were eating poplar trees containing salicylic acid, which is the raw material of aspirin, and the blue mold that produces penicillin, trying to cure tooth abscess and bacterial stomach infection It is expected to be.

Also, because there are traces of saliva exchanging, the research team thinks that "Neanderthal people were kissing, or were chewing foods given by mouth-to-mouth". According to Hervé Bocherens, a paleontologist at Tabingen at Eberhard Karl University in Germany, the database of DNA used for analysis is not accurate as it does not contain extinct species that Neanderthales would have eaten There are possibilities, there are also studies showing that both groups were eating meat. Bocherens says, "It is too early to conclude the diet of Neanderthals at the present time."
