- Fossil site of extinct human cousin may have been all female
A study of Homo naledi fossils from South Africa's Rising Star Cave system found no male markers in 23 analyzed teeth, suggesting the Dinaledi Chamber may be an all-female fossil site. Researchers used protein analysis to detect the absence of Amelogenin-Y, a male-specific protein, raising questions about the species' burial practices and potential sex-specific mortuary behavior.
