Neanderthals were hunters in western Eurasia for more than 200 thousand years in glaciers and inter-regional periods until the destruction of 40,000 years ago. Although some of the anatomical regions of the dead are well-known, however, these elements are less fragile and are not well preserved in excavations as other people, such as vertebrate columns and walls, are less popular. In 1983, the Neanderthal skeleton (officially known as "Kebara 2" and "Moshe") belonged to a young Neanderthal man who died about 60,000 years ago at the Kebara Square (Mount Carmel, Israel). This skeleton does not keep the crane, because the crane has been destroyed after some time after burial, otherwise the rituals of rituals. However, all the vertebrae and walls remain, as well as other delicate anatomical regions, such as the pelvis or gioia bone (neck bone attached to some muscle of the tongue). Thus, the fossil remains the most complete chest cavity.

New methods of statistical and virtual transformation allowed researchers to obtain new information published in a reputable journal Nature Relations.

For more than 150 years, a group of nanoparticles has been discovered in many parts of Europe and Western Asia (including the Middle East), and since 1856, the group has been identified as the first wall of this human morphology. Over the past decade, virtual rebuilds have become a new tool for excavations. This method is particularly useful with delicate fossils such as chest and vertebrate. Approximately two years ago, this research team had rebuilt the Neanderthal human vertebrae; it reflects the preserved spine of Kevara 2, with uncertain curves on these people, compared to Homo sapiens. The work published in the book Human Paleontology and Early Paleontology has shown that the spine is tougher than modern humans.

For this breast virtual model, researchers have monitored skeletal skeletons of Kebara 2 and Telemedicine CT (computerized axial tomography) scanning of the vertebrae, walls and hip bones at Tel Aviv University. After all the anatomical items were assembled, virtual rebuilding was made using 3D software specially designed for this purpose. "It was a great deal of work," says Prof. Alon Barash of Bar Ilan University in Israel. "We had to scan each of the spinal and all the ribs and then re-collect them in the form of virtual 3D."

"It was necessary to cut and deform parts of the deformation in the recovery process, and on the other hand it was necessary to define well-preserved walls to replace the bad ones." Ikerbasque's researcher, Aser Gomez-Olivia, at the University of Basi.

"The difference between Neanderthal and modern man's chest is staggering," said Daniel Garcia-Martinez and Marcus Bastier, researchers at the National Museum of Natural Sciences (MNCN-CSIC). "Neanderthal vertebral palsy is much more common than the wall, which provides stability and broader wider than in the chest," adds Michel Argyle (UPV / EHU).

"The lower extremities of the Neanderthals and the more horizontal wall of the walls are more based on diaphragm for Neanderthal breath as shown in its restoration," says Ella Bedel of the Academic College of On. "Modern people rely on the diaphragm as well as the expansion of the wall, where new technologies and methodologies for excavation research give new insight into the disappearance of species."

This new information coincides with recent studies of the largest lung capacity of Neanderthals, published by two authors of this study: Markus Bastir and Daniel Garcia Martinez (MNCN Virtual Anthropology Laboratory), pulmonary benefits in Neanderthals.

Patricia Cramer, of the University of Washington, said: "We hope this is a culmination of a 15-year study of the Neanderthal Breast, and future genetic analyzes will provide further details about neurasthenia's respiratory physiology."
