Panthera leo leo
Panthera leo leo is a lion subspecies present in West Africa, northern Central Africa and India. In West and Central Africa it is restricted to fragmented and isolated populations with a declining trajectory. It has been referred to as the northern lion.
Results of a phylogeographic study indicate that lion populations in West and Central African range countries are genetically close to populations in India, forming a major clade distinct from lion populations in Southern and East Africa. In 2017, the Cat Classification Task Force of the IUCN Cat Specialist Group subsumed lion populations according to the major clades into two subspecies, namely P. l. leo and P. l. melanochaita. Within P. l. leo three subclades are clearly distinguishable. One from Asia, which includes the extinct Barbary lions of North Africa, another one from West Africa and a third one from Central Africa, north of the rainforest belt.
P. l. leo is regionally extinct in North Africa, southern Europe, and West Asia. Asia's sole lion population lives in and around Gir National Park, India. The West African lion population is geographically isolated and numbers fewer than 250 mature individuals. It is listed as critically endangered on the IUCN Red List.
A lion from Constantine, Algeria, was the type specimen for the specific name Felis leo used by Carl Linnaeus in 1758. In the 19th and 20th centuries, several lion zoological specimens from Africa and Asia were described and proposed as subspecies:
In 1930, Reginald Innes Pocock subordinated the lion to the genus Panthera when he wrote about Asiatic lion specimens in the zoological collection of the British Museum of Natural History.
In the following decades, there has been much debate among zoologists on the validity of proposed subspecies:
In 2017, the Cat Classification Task Force of the IUCN Cat Specialist Group subsumed lion populations in North, West and Central Africa and Asia to P. l. leo, based on results of genetic research on lion samples.
Since the beginning of the 21st century, several phylogenetic studies were conducted to aid clarifying the taxonomic status of lion samples kept in museums and collected in the wild. Scientists analysed between 32 and 480 lion samples from up to 22 countries. They all agree that the lion comprises two evolutionary groups, one in the northern and eastern parts of its historical range, and the other in Southern and East Africa; they are estimated to have genetically diverged between 245,000 and 50,000 years ago. Tropical rainforest and the East African Rift possibly constituted major barriers between the two groups.
