From Carole Rushall, Middlesbrough, North Yorkshire, UK
The skull of a small child found on a ledge in a cave with no signs of carnivore activity or large-scale water movement doesn’t indicate to me that it is firm evidence of the early human species Homo naledi burying its dead (13 November, p 9). Young children hide in nearly inaccessible places as part of their games. Child’s play could be a plausible explanation.
