Researchers have discovered new Neanderthal remains at the Cova de l'Arbreda de Serinyà in Spain, including three human teeth corresponding to a child, an adolescent, and an adult Neanderthal individual. The teeth date back to different periods, with two of them being at least 120,000 years old and the third dating between 71,000 and 44,000 years ago. The analysis of the remains suggests that the Neanderthals who inhabited the cave may have alternated between short seasonal stays and longer settlements, indicating an adaptation to climatic and environmental changes. The findings provide valuable information about the presence and subsistence strategies of Neanderthals in the Iberian Peninsula.
