Sima de los Huesos

Sima de los Huesos, located in Spain's Sierra de Atapuerca, is a prehistoric site famous for its rich fossil finds. Discovered in the late 20th century, it contains the remains of at least 28 individuals, dating back around 430,000 years. These bones, linked to early humans known as Homo heidelbergensis, provide invaluable insights into human evolution, including evidence of their health, diet, and social behavior. The site is crucial for understanding how early humans lived and interacted, as well as their eventual transition to modern Homo sapiens.
