Jaguarundi Eyra Cat
|
The jaguarundi is closely related to the much larger and heavier cougar, having a similar genetic structure and chromosome count. While both species are in the genus Puma it is sometimes classified under the genus, Herpailurus, and until recently both cats were classified under the genus Felis.
According to a 2006 genomic study of Felidae, an ancestor of today's Leopardus, Lynx, Puma, Prionailurus, and Felis lineages migrated across the Bering land bridge into the Americas approximately 8 to 8.5 million years ago. The lineages subsequently diverged in that order.
Studies have indicated that the cougar and jaguarundi are next most closely related to the modern cheetah of Africa and western Asia, but the relationship is unresolved. It has been suggested that ancestors of the cheetah diverged from the Puma lineage in the Americas and migrated back to Asia and Africa, while other research suggests the cheetah diverged in the Old World itself. The outline of small feline migration to the Americas is thus unclear.
