The fact that the skeletons were buried with stone tools and carved jewelry of ivory and bone suggests a level of cultural sophistication that is characteristic of the Cro-Magnon culture, which existed around 40,000-10,000 years ago. Additionally, the anatomical similarity to modern humans suggests that these skeletons are not Neanderthals (who lived in Europe and Asia around 400,000-40,000 years ago), Homo floresiensis (who lived in Indonesia around 100,000-60,000 years ago), Homo erectus (who lived in Asia around 1.8 million-300,000 years ago), or Australopithecus afarensis (who lived in Africa around 3.9-2.9 million years ago).
