Compared with modern people, adult Neanderthals have shorter, deeper, and wider breasts. These anatomical features are related to the Neanderthal body, which has a wide pelvis, strong bones and strong muscles. This is also related to their need for a lot of energy and oxygen during metabolism.
Paleoanthropologist Daniel García-Martínez collaborated with international colleagues. They used virtual reconstruction and traditional geometric measurement methods to reproduce the chest contours of 4 Neanderthals, including three-dimensional chests from birth to about three years old. structure.

Research results show that the thorax of an infant Neanderthal, like other anatomical regions such as the mandible, has shown characteristics different from those of modern human species. The thorax of an infant Neanderthal was the same size as that of a modern adult. This result shows that Neanderthals are shorter, deeper, and larger ribcage is not the result of development, but is determined by genes.
