Question

An anthropologist compares the remains of H. neaderthalensis to earlier hominid species, like H. habilis, and to the contemporary and later species H. sapiens. He believes that H. neanderthalensis were the first hominids to bury their dead. Which of the following would be a valid reason to question the reliability of this idea?

Finding a fossil of H. habilis beneath fossils of H. neanderthalensis

Finding fossils of H. neanderthalensis skeletons in isolation

Finding burial sites of modern H. sapiens in the same region as H. neanderthalensis fossils

Finding burial sites of H. habilis
