JERUSALEM, Nov. 5 (Xinhua) – Israeli researchers have reconstructed the Neanderthal's spine and rib cage in 3D and found that they were not as curved and clumsy as previously thought , reported Sunday the "Ynet" in Hebrew.
Neanderthals are an extinct archaic human species that appeared about 400,000 years ago and disappeared about 30,000 years ago.
They lived mainly in Europe and Western Asia and the Land of Israel was their southernmost border.
Neanderthals were hunter-gatherers who lived in caves, lit fires, made flint tools, and survived several ice ages.
Researchers from Bar-Ilan University and Ono University College, both located in central Israel, have created a three-dimensional model of a Neanderthal skeleton found in a cave in northern Israel – based on tomodensitograms of fossilized bones.
According to the researchers, the reconstruction shows that the Neanderthals were standing, had a wide chest and were breathing mainly through the diaphragm.
The study revealed that the direction of Neanderthal coasts is more horizontal than in modern man.
The combination of horizontal ribs with a large diaphragm shows that Neanderthals primarily need the diaphragm to breathe, while modern humans rely on a combination of diaphragm work and rib movement.
The thoracic structure is a key to understanding the integration of Neanderthals into the territory in which they lived, as it indicates their ability to move, breathe and balance.
Understanding how Neanderthals integrate into their environment helps to better understand evolution.
In addition, the Neanderthal movement has a direct effect on their ability to rely on existing resources in the environment in which they lived and on their chances of survival. Enditem
