Briefings

A 2026 study published in Molecular Phylogenetics and Evolution analyzed genetic data from India's 'big four' snakes to clarify their evolutionary relationships. The research indicates that the spectacled cobra (Naja naja) remains a single species across South Asia, but regional variations in color and markings suggest distinct evolutionary lineages. The study aims to identify specific divergence times and geographic origins for these groups, though the evidence currently focuses on the spectacled cobra's regional structure rather than the entire group.

Key points

• The spectacled cobra (Naja naja) is currently classified as a single species across South Asia, despite regional differences in color, hood markings, and venom composition.
• The study published in Molecular Phylogenetics and Evolution in 2026 uses genetic data to parse out evolutionary lineages and estimate when and where these regional groups diverged from their ancestors.

Context and limitations

The evidence is limited to the spectacled cobra's regional structure; the study does not provide data on other 'big four' snakes or the complete genetic history of the entire group.
