India's cobras share genetic ties across the mainland, while Sri Lankan cobras form a distinct genetic lineage

The spectacled cobra (Naja naja) is one of India's "big four" snakes responsible for most serious snakebite cases. It is currently considered one species, which lives across much of South Asia, with regional differences in color, hood markings and venom. However, it's still unclear which regional cobra populations represent separate evolutionary groups. A new study published in Molecular Phylogenetics and Evolution has helped parse out which groups have different lineages, and when and where they may have diverged from their ancestors.
