Proteomic analysis of Homo naledi fossils indicates all known specimens are female
Analysis of dental remains from South African cave systems has revealed that all examined specimens of the species Homo naledi were female. These findings, based on proteomic analysis of tooth proteins, suggest the individuals may have been placed in the Rising Star cave deliberately.

Proteomic analysis of dental remains found in a South African cave system has identified exclusively female protein markers among samples of the species Homo naledi. The Times of India reports that these results were obtained from analyzing ancient teeth, providing biological evidence for the sex of the hominid individuals.
The study focused on 23 specific specimens located within the Rising Star cave. According to New Scientist, the fact that every individual identified in this location is female strengthens the case that the remains were placed in the cave deliberately rather than being the result of accidental accumulation. This finding suggests a level of intentionality regarding how the bodies were handled or deposited after death.
Homo naledi was first discovered in 2015 and has since been studied for its unique anatomical features and estimated age of approximately 2.5 million years. While previous research focused on the physical characteristics of the species, this new molecular data provides information on population demographics. The use of protein markers allows researchers to determine biological sex in cases where skeletal structures may not provide clear evidence.
Why this matters
The discovery provides potential evidence regarding the social behaviors and cultural practices of early hominids. If the remains were intentionally placed, it suggests complex interactions or specific traditions regarding death and disposal within these populations.
What's confirmed / what isn't
Multiple sources confirm that proteomic analysis of dental remains from the Rising Star cave shows only female protein markers across all 23 Homo naledi specimens. The conclusion that these items were placed in the cave deliberately is a finding reported by New Scientist based on this specific data.
Background
Homo naledi is an archaic hominid species first discovered in 2015 in the Rising Star cave system of South Africa. It is known for its distinct anatomical features and is estimated to be approximately 2.5 million years old.
