A discovery in a cave has shed light on the burial practices of an ancient human species, with evidence suggesting they may have been the first to bury their dead. The findings include a large number of ancient hominins, with some reports indicating they are all female, although the species itself is not clearly identified and may be one of several, including homo naledi or denisovans. The discovery also hints at possible interbreeding between different ancient human species, adding to the complexity of human evolutionary history.
