The DNA secrets of a medieval cave-dwelling community
Briefly

Inbreeding and occasional violence characterized the medieval Christian community in caves of the Iberian Peninsula, shedding light on their ancestry and diseases.
Our genetic analysis reveals a unique perspective on the community, indicating social dynamics and connections often overshadowed by the major urban centers' historical narratives.

Despite limited evidence, the exploration of why these communities favored caves opens new discussions about their lifestyles beyond the typical hermit or religious narratives.
