Cape lion
The Cape lion (''Panthera leo melanochaitus'') is an extinct subspecies of lion,〔Yamaguchi, N. (2000). (The Barbary lion and the Cape lion: their phylogenetic places and conservation ). African Lion Working Group News 1: 9–11.〕 or possibly a former population of Southeast African lions (''Panthera leo krugeri'').
==Taxonomy==
As with the Barbary lion, several people and institutions claim to have Cape lions. There is much confusion between Cape lions and other dark-coloured long-maned captive lions. Dark-maned lions in captivity today have been bred and cross-bred from lions captured in Africa long ago, with examples from all of these 'subspecies'. Mixed together, hybridized, most of today's captive lions have a 'soup' of alleles from many different lion subspecies.〔Maas, P.H.J. 2006. Cape lion – Panthera leo melanochaitus. The Extinction Website. Downloaded on 2 July 2006.〕
Early authors justified "distinct" subspecific status of the Cape lion because of the seemingly fixed external morphology of the lions. Males had a huge mane extending behind their shoulders and covering the belly, and the lions' ears also had distinctive black tips. However, nowadays it is known that various extrinsic factors, including the ambient temperature, influence the colour and size of a lion's mane. Results of mitochondrial DNA research published in 2006 do not support the "distinctness" of the Cape lion. It may be that the Cape lion was only the southernmost population of the extant Southeast African lion or Transvaal lion.
