The body proportions of neanderthals may have arisen as adaptations to a HARSH AND CONTINUOUSLY CHANGING environment. Neanderthals that have evolved through millions of years have developed skills and techniques in order for them to eat, live in good conditions, and protect themselves from dangers of the environment. As such, their physical bodies have also evolved through the activities that they do on a regular basis.
