Research overview: the jaguar's position among the big cats

The jaguar, the only Panthera species in the Americas, occupies an informative position in big cat phylogeny. This overview explains how molecular data place the jaguar within the genus Panthera, closely allied with the lion and leopard rather than with the New World cats among which it lives. It discusses evidence that the jaguar's ancestors dispersed into the Americas from Eurasia, and that introgression occurred among Panthera lineages, including signals involving the jaguar and lion. The piece highlights how the jaguar exemplifies the reticulate, intercontinental history of the big cats, with its American distribution reflecting dispersal rather than local origin. It connects to broader genomic work showing that the Panthera radiation involved both branching and gene flow across lineages now separated by oceans and continents.
