Linsang

Linsangs is an originally Javanese name applied to four species of tree-dwelling carnivorous mammals. The two African species belong to the family Viverridae, the two Asiatic species belong to the family Prionodontidae.

Both linsang genera (the African Poiana and the Asian Prionodon) were formerly placed in the subfamily Viverrinae (of Viverridae), along with several other genera, but recent research suggests that their actual relationships may be somewhat different. The linsangs are remarkable for their morphological resemblance to cats, family Felidae, which is greater than in the other viverrids. As the relationship between linsangs and cats was thought to be rather distant (the two groups belonging to different families within the superfamily Feliformia), this was considered an example of convergent evolution. However, DNA analysis indicates that while the African linsangs (Poiana) are true viverrids closely related to the genets, the Asiatic linsangs (Prionodon) are not and may instead be the closest living relatives of the family Felidae. The similarities between Asiatic linsangs and cats are thus more likely to be due to common ancestry, while the similarities between the two genera of linsangs must be convergent.
