The biggest unsolved anthropological story of the 21st century is the problem: What killed off the Neanderthals and why did Homo sapiens increase even as Neanderthals withered to extinction?
Researchers and scientists are working to assume it some plague specific only to Neanderthals which began to its disintegration? Was there some cataclysmic event in their countries of Eurasia that lead to their disappearance?
‘Ancient origins’ suggests a new study from a team of physical anthropologists and
Head and neck anatomists recommend a less exciting but both deadly cause. Distributed online by the journal, The Anatomical Record,
the study, Building the Neanderthal Eustachian Tube: New Insights on Disease Susceptibility,
Health Cost and Extinction suggest that the real culprit in the demise of the Neanderthals was not some exotic pathogen.
Instead, the authors believe the path to extermination may well have been the most natural and kind of childhood diseases that is, chronic ear infections.
Co-investigator & Downstate Health Sciences University Associate Professor Samuel Márquez, PhD, said, “It may sound far-fetched, but when we, for the 1st time,
built the Eustachian tubes of Neanderthals, we found that they are primarily similar to those of human infants.
Middle ear diseases are nearly universal among infants because of the low angle of an infant’s
Eustachian tubes are likely to retain the otitis media bacteria that cause these diseases – the same flat angle we found in Neanderthals.”
The study also suggests that in this age of medicines, these infections are easy to treat and relatively good for human kids.
Additionally, around age 5, the Eustachian devices in human children grow, and the angle converts more critical, allowing the ear to drain, all but killing these recurring viruses beyond first childhood.
The structure of the Eustachian pipes in Neanderthals do not change with age, which means these ear diseases and their difficulties,
including-respiratory infections, hearing loss, pneumonia, and worse, would not only become fixed but a lifelong threat to overall fitness and survival.
“It’s not just the warning of dying of an infection,” told Dr Márquez. “If you are regularly ill, you would not be as fit and active in playing with your H. Sapien relatives for food and other supplies. In a world of the continuance of the fittest, it is no wonder that new man, not Neanderthal, prevailed.”
“The strength of the study lies in building the cartilaginous Eustachian tube,” Told Richard Rosenfeld, MD, MPH, MBA, Distinguished Professor Chairman of Otolaryngology at SUNY Downstate. “This unique and before unknown knowledge of middle ear function in Neanderthals is what enables us to make new conclusions regarding the impact on their health and fitness.”
