The skull displays many of the "classic" examples of Neanderthal anatomy, including a low, sloping forehead and large nasal openings.The teeth are well preserved and the incisors are heavily worn down, suggesting they were used to hold objects.

His leg and foot bones make it clear that Neanderthals walked upright like modern humans.

[3] The hands and fingers have been linked to rare conditions and the teeth have also been the subject matter to many human evolution theories.

Nonetheless, the La Ferrassie 1 remains have proved to be beneficial in studying evolution over time.

John A. Wallace, an Assistant Professor in the Department of Anatomy at Queen's University was the first to ask the question, "Did La Ferrassie 1 use his teeth as a tool?

"[6] This question would explain the changes to face shape that followed La Ferrassie 1 and the extreme wear that can be seen.

Wallace noted that changing face shape due to teeth use is a case of selective mechanism.

[4] Pierre-Francois Puech also noted that the cheek teeth were very similar to present-day humans, and La Ferrassie 1 also had a long mandible of 126 mm.

It is also important to note that La Ferrassie 1 was also discovered to have a case of hypertrophic pulmonary osteoarthropathy, also known as HPO.
