EAR INFECTIONS: Scientists claim that complications of common childhood illness could have caused the extinction of a mystery
- It is thought that the lack of drugs 40,000 years ago saw the archaic species
- Smaller ears also meant that bacteria clogged in a small space
- This is thought to have led to breathing and hearing problems and pneumonia
According to scientists, ear infections have probably killed Neanderthals, according to scientists who claim to have cracked the mystery surrounding the disappearance of this species.
While antibiotics are taken for granted in the modern world, it is thought that a lack of sophisticated drugs 40,000 years ago saw archaic species suffer from common childhood illness and then perish.
In addition, Neanderthals were more prone to getting an ear infection because they had smaller ears, providing a narrower space for clogging bacteria.

Neanderthals were more likely to get an ear infection because they had smaller ears, providing a narrower space for clogging bacteria.
According to scientists, ear infections have probably killed Neanderthals, according to scientists who claim to have pierced the age-old mystery of the extinction of the species.
The results, published in Anatomical Record Journal, were obtained by scientists based in New York.
Professor Samuel Márquez of the Downstate University of Health Sciences said: "This may seem far-fetched, but when we first reconstructed the Neanderthal Eustachian tubes, we have discovered that they looked remarkably like those of infants.
"Middle ear infections are almost ubiquitous in infants because the flat angle of an infant's Eustachian tube is likely to retain the otitis media bacteria that cause these infections – the same flat angle that we found in Neanderthals.
In modern times, the Eustachian tube in children begins to lengthen around the age of five and the angle becomes more acute.
While antibiotics are taken for granted in the modern world, it is thought that a lack of sophisticated drugs 40,000 years ago has seen archaic species suffer and perish
This allows the ear to drain, eliminating almost all of these recurring infections beyond early childhood.
But unlike modern humans, the structure of Eustachian tubes in Neanderthal did not change with age, which meant that these chronic ear infections persisted.
Dr. Márquez said: "This is not just the threat of dying from an infection. If you are constantly sick, you will not be as fit and efficient as to compete with your Homo sapien cousins for food and other resources.
"In a survival world of the fittest, it is no wonder that modern man, and not Neanderthal, has prevailed."
Dr. Richard Rosenfeld added, "This new and previously unknown understanding of Neanderthal's middle ear function allows us to draw new conclusions regarding the impact on their health. and their physical form. "
