- The Skull is known to show Interbreeding that took place with neandertals and their relatively healthy population.
- The Fragment shows that there was a possibility of cannibalism in that area.
It shows that possible cannibalism took place as there were Cutmarks on various hominin bones found at Atapuerca mirror.
The relatively healthy population was found out through the study of the dentition of the Atapuerca hominins by anthropologists. It gave them a view into their diet and overall health.
