Helpp:) An anthropologist compares the remains of Homo neaderthalensis to earlier hominid species, like Homo habilis, and to the contemporary and later species Homo sapiens. He believes that Homo neanderthalensis were the first hominids to bury their dead. What would make this conclusion incorrect?

Finding a fossil of Homo habilis beneath fossils of Homo neanderthalensis
Finding fossils of Homo neanderthalensis skeletons in isolation
Finding burial sites of modern Homo sapiens in the same region as Homo neanderthalensis fossils
Finding burial sites of Homo habilis on different continents
