LONDON: India could soon help bring back an extinct lion species. DNA tests by an international team of scientists has confirmed the lions in India have close genetic links with the now extinct Barbary lions.
This means that "reseeding" Indian lions could bring back the extinct species and reintroduce lions into North Africa.
Less than 400 Asiatic lions survive at present on the Kathiawar Peninsula of India and the species is listed as endangered by the International Union for the Conservation of Nature.
Barbary lions of North Africa — including mountainous regions — extending from Egypt to Morocco were also called the Atlas lions and had the most spectacular physical features of all lion species. The lion's extensive mane made it look majestic. It was a lot larger with differently-coloured eyes to other lions.
Dr Ross Barnett of Copenhagen University, who had started the research during his days at Durham University in UK, sequenced the DNA from the skulls of two Barbary lions once held in Britain's Tower of London. It has helped reveal the origin of modern lions.
The skulls of these lions dated as living in the 14th and 15th centuries were discovered preserved in the Tower of London's moat.
Dr Barnett said he was surprised by the incredibly close relationship between the extinct Barbary lion from North Africa and the Asian lion from India. This he says could now get conservationists start talking about resurrecting the subspecies and reintroducing lions into North Africa"
Despite the large geographical distances between them, the Indian lions seem to be closely related to Iranian lions and the Barbary lions of North Africa.
The study says: "In the tiger, another charismatic felid species, studies of ancient mitochondrial DNA have suggested a close relationship between the extinct central Asian Caspian tiger and the extant Amur tiger. This has allowed conservationists to discuss the translocation of Amur tiger stock to occupy the former range of the Caspian tiger with support from the World Tiger Summit. Similarly, if no examples of purebred Barbary lions can be found within the zoo population, there might be scope for restoration of the North African lion population using the closely related Indian lion."
A genetic analysis of living lions and museum specimens confirms modern lions' most recent common ancestor lived around 124,000 years ago.
Dr Barnett said, "Understanding the demographic history of a population is critical to conservation. This is particularly true for the lion which as a consequence of millennia of human persecution, has large gaps in its natural distribution and several recently extinct populations. We sequenced mitochondrial DNA from museum-preserved individuals including the extinct Barbary lion and Iranian lion as well as lions from West and Central Africa. We have identified deep, well-supported splits within the mitochondrial phylogeny of African lions."
The lion had one of the largest geographical distributions of any terrestrial mammal during the Late Pleistocene, ranging from southern Africa through northern Eurasia to Central America. Widespread hunting and anthropogenic changes to lion habitat are continuing to reduce lion populations across their entire range.
The research says: "From the DNA analysis, we identified four new mitochondrial haplotypes: one from North Africa, one from a suspected Barbary lion present in medieval London, one from Iran, and one from Senegal. Four of the six Barbary lions exhibited sequence identical to that of the extant Indian lion."
"International bodies currently recognize only two lion conservation units: African and Asian lions. The data clearly show that Asian lions are nested within the diversity present in Central, West and North Africa. Of particular concern are the central African and western African populations, which may be close to extinction, with estimates of 800 lions in West Africa and 900 lions in Central Africa. The close phylogenetic relationships among Barbary, Iranian, and Indian lion populations are noteworthy given their considerable geographical separation. The restoration of the extinct North African Barbary lion has attracted the attention of conservationists both inside and outside North Africa," it added.
