The cheetah is not African but American


The cheetah is an iconic predator found on the plains of Africa. It streaks like lightning after its prey at speeds of up to 100km/h and is seen in countless wildlife documentaries about the continent of Africa but, it now appears that the animal is not really African at all.
Latest research has revealed that it actually migrated from North America around 100,000 years ago during the last Ice Age before becoming isolated in Africa.
This has been reported in nzherald.co.nz dated 11 December 2015.
A genetic study has found the cats actually evolved from the North American puma and went for an epic journey across a landbridge into Asia. From there they traveled south to Africa and, in the course of these happenings, their populations dwindled. This led to a dramatic reduction in their gene pool as the animals were forced into incestuous mating.
In order to arrive at these findings, researchers from St Petersburg State University in Russia have sequenced the genome of seven cheetahs from Tanzania and Namibia, including a male.
Incidentally, the endangered species is currently found in the wild in eastern and southern Africa.
