First-Ever Case of Down Syndrome in Neanderthals Unveils Altruistic Behavior

In a groundbreaking study, researchers have uncovered evidence of Down syndrome in a Neanderthal child named “Tina,” found at Cova Negra in Valencia, Spain. This discovery challenges previous notions about Neanderthal social behavior.

Research Details

  • Location and Significance: Tina’s remains were unearthed at Cova Negra, known for its significant Neanderthal discoveries along the Mediterranean coast.
  • Research Team: Led by anthropologists from the University of Alcalá and the University of Valencia, Spain.
  • Innovative Techniques: Micro-computed tomography scans were used to create a detailed 3D model of Tina’s inner ear region, revealing congenital pathology associated with Down syndrome.

Implications for Neanderthal Behavior

  • Evidence of Altruism: Tina’s survival, despite severe disabilities, suggests Neanderthals practiced altruistic behavior by caring for vulnerable members of their community.
  • Community Support: The findings indicate a structured social framework where individuals received care, challenging previous assumptions of Neanderthals as purely survival-focused.

Expert Opinions

  • Professor Rolf Quam applauded the study for its integration of archaeological excavations and medical imaging, emphasizing its significance in understanding Neanderthal behavior.
