  • 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.

The interbreeding with the Neandertals was shown through the Nuclear DNA that was gotten from bones and teeth of bones found at Sima de los Huesos
