"Study reveals genetic divergence in cobra populations separated by sea" — Mongabay · Science & Medicine
This Mongabay story reports on a new phylogeographic study of the Indian spectacled cobra (Naja naja), one of India's medically important 'big four' venomous snakes. Using multi-locus DNA data, the researchers found that cobra populations separated by the sea between India and Sri Lanka have diverged genetically, even though populations across mainland India show limited regional genetic structuring and extensive sharing.
The claim rests on a peer-reviewed phylogeographic study of Naja naja, apparently published in Molecular Phylogenetics and Evolution, and Mongabay is reporting directly on that primary paper, so the coverage is close to the source. The headline compresses a more nuanced result: mainland Indian populations are weakly structured and share many mitochondrial haplotypes, but the genetic break across the sea barrier is the standout finding.
Published on 13 October 2026, this is fresh coverage of a newly released study, not resurfaced older material.
