Research overview: divergence of Geoffroy's cat and the kodkod

Geoffroy's cat and the kodkod (guigna) are closely related small cats of southern South America whose relationships illuminate the Leopardus radiation. This overview examines their phylogenetic placement and divergence, with molecular data showing they are sister or near-sister species that split relatively recently. It discusses Geoffroy's cat's wide range across the southern cone and the kodkod's restricted distribution in Chile and Argentina, the smallest cat in the Americas. The piece explains how these species, along with the southern tigrina, form a closely allied group within Leopardus marked by hybridization in contact zones. It connects to broader themes of rapid Neotropical felid diversification and how molecular phylogenetics resolves relationships among recently diverged, morphologically similar small cats that traditional taxonomy struggled to distinguish.
