Fossil site of extinct human cousin may have been all-female

Researchers have uncovered intriguing evidence suggesting that a South African cave system used by Homo naledi may have been an all-female burial site. Protein analysis from the teeth of at least 20 individuals revealed no male markers, indicating the cave might be the first known sex-specific burial site by a non-human species. This discovery not only reshapes our understanding of Homo naledi behavior but also highlights the complexity of social structures among our ancient relatives. The findings could provide deeper insights into the evolution of social behaviors and the roles of different sexes in prehistoric communities.
