Neanderthals may have disappeared from colds

According to the new hypothesis, the Neanderthals could have become extinct by the epidemic catarrhal diseases
The Rapid development of medicine of the XX century gave the world many benefits, chief of which was the almost complete freedom from many colds. So, modern man knows that at the first attack of acute respiratory disease or simply to visit the pharmacy, buying there a couple of simple means, and then a couple of days to stay in bed, occasionally sipping tea with raspberries. However, this happy scenario of events was so not always. In 1918, the world was shocked with terrible flu epidemic that claimed the lives of millions of people around the world. What to say about those who lived in ancient times? According to the new theory of the anthropologists, could completely disappear as a species as a result of ordinary colds, which are currently more common in infants than in adults.
Why the Neanderthals died out?
Despite the fact that the extinction of the Neanderthals as a species still remains a mystery to scientists, it is believed that the main reason for the extinction of this unique species of human could become a regular . So, the cause of mass death of Neanderthals, scientists tend to think of infectious disease, called chronic Eustachian. Usually the Eustachian invoked due to an inflammatory process, formed in the nasal cavity in diseases such as sinusitis, rhinitis or sore throat. At the same time, the symptoms are similar to symptoms of otitis media, causing the patient a lot of discomfort.
the appearance of the auditory tube adult
So why did the Neanderthals could easily disappear as a result of infectious disease, occurring most often in young children? The fact that it is a detailed reconstruction of the skull , scientists have detected previously unnoticed peculiarity in the structure of the auditory tube connecting the middle ear and the nasopharynx of the person. Auditory tube ancient man was surprisingly similar to the structure similar to the auditory tube modern baby. Because of its several unsuccessful horizontal arrangement, as well as the relatively short length of the auditory tube baby is often the most vulnerable to infections of the body until until the baby reaches the age of 1 year.
Due to the fact that the children of CRO-magnons as they get older acquire the more advanced structure and location of the hearing body, they, thereby, were able to gain some evolutionary advantage over Neanderthals, who retained the original structure of the ear throughout life. Any ear infection for members of the Neanderthal tribes could result in very serious consequences, including death. Thus, small evolutionary detail could lead to the fact that at the present time we cannot boast of a friend of a Neanderthal in its immediate environment. Although, perhaps, I would like to.
