Researchers, led by Lee Berger, had claimed in a Netflix documentary that the species buried its dead, used fire, used tools, and made rock art.
I could not find a single reviewer who accepted the claims of the papers. They were harshly critical of claims of intentional burial of the skeletons.
Berger et al.’s claims about the species have been disputed and their idea that it lived 2-3 million years ago was exaggerated by a factor of 10.
The dead body has value because the human person does. How we treat our dead reflects our views on what we think about the living.
If a Neanderthal walked down the street, appropriately dressed, you probably wouldn’t notice.
