The article discusses findings related to hominin species, particularly focusing on the absence of the AMELY gene, suggesting female samples but acknowledging potential identification issues. Researchers examined 425 amino acid locations to clarify relationships among species like Paranthropus and Homo. They concluded that the observed amino acid variations might not definitively indicate relationships due to insufficient samples. Notably, Paranthropus robustus appeared closely related to the Homo genus, though researchers stressed that more data is needed to confirm these preliminary insights.
The absence of AMELY suggests that a sample is female, but it isn't definitive due to potential identification issues and rare males lacking the gene.
The research indicates that 16 species-specific amino acid variations among hominins could help clarify relationships between various hominin species, particularly within Paranthropus.
