Every Homo naledi we know of is female, and the implications are fascinating
A recent study of dental enamel proteins from 23 Homo naledi teeth shows that every individual with preserved teeth is genetically female. The researchers found only the X‑chromosome protein AMELX and no trace of the male‑specific AMELY, making the odds of this pattern occurring by chance extremely low. The findings support the hypothesis that Homo naledi may have engaged in deliberate burial practices, reflecting cultural behavior.
- ▪The analysis of 23 teeth from at least 20 Homo naledi individuals revealed only the X‑linked protein AMELX and no Y‑linked AMELY.
- ▪The probability of all sampled individuals being female by random chance is about 0.0000954 percent, according to the authors.
- ▪The study suggests that Homo naledi may have intentionally placed their dead in the Rising Star Cave, indicating possible cultural or ritual behavior.
- ▪All known Homo naledi specimens with dental material, including infants, are female, which is unusual compared to other primate groups.
- ▪The findings add weight to the argument that Homo naledi practiced some form of burial rather than the remains being accidental.
