Neanderthals died out because of the big eyes, dark nights and lack of friends March 13, 2013
Several previous studies have shown that the brain size of Neanderthals actually not all that different from the size of the brain of modern man. However, due to the latter to the research, scientists have found that the structure of the Neanderthal brain was still structured in such a way that in the end she was the cause of their extinction.
More precisely, a group of scientists from Oxford University and the Natural History Museum in London, led by Eylundum Pierce (Eiluned Pearce) state that, in contrast to the modern man, Neanderthals used their brains in the first place for the visual interpretation of their environment. And because they lived mainly in the northern latitudes, where it is very dark nights, they have to actively develop the part of the brain responsible for vision. That is the conclusion they came after the discovery of fossils whose characteristic feature was the presence of very large eye sockets, and therefore once the big eyes.
Scientists believe, despite the fact that the brains of Neanderthals used to assess and move on rather dangerous environment, ultimately it is their undoing. That’s because they have never used the brain for social purposes, and therefore never met in a crowded group, which would allow them to develop.
Study author Eylund Pearce commented:
“Since Neanderthals lived in the higher latitudes, and had a large figure compared to modern people, a large part of their brain has evolved to Neanderthal better seen and managed his body, and not to perform other very useful for the development of the function such as social interaction. Small social groups eventually reduced the effectiveness of Neanderthals struggle with difficulties Eurasian life. In other words, they did not have any friends who could always come to the rescue. ”
