We demonstrate that these extant Iranian cheetahs are an autochthonous monophyletic population and the last representatives of the Asiatic subspecies We advocate that conservation strategies should consider the uncovered independent evolutionary histories of Asiatic and African cheetahs, as well as among some African subspecies.This would facilitate the dual conservation priorities of maintaining locally adapted ecotypes and genetic diversity.
Cheetahs (stock image of three cheetahs pictured) are an iconic African predator, but a new genetic study has revealed the animals are actually related to North American pumas and they migrated to Africa during the last Ice Age around 100,000 years ago Modern cheetahs (pictured) are currently endangered in the wild and many of their problems may stem from the epic migration their ancestors made from North America, that saw their population size reduce rapidly, leaving their gene pool severely depleted Sony SRS-XB40 has a built-in multi-coloured line light, speaker lights and a flashing strobe.
It features 24 hours of battery life and claims to be a 'mini-disco on the move'.
This has been suggested to be the consequence of a demographic bottleneck 10 000–12 000 years ago (ya) and also led to the assumption that only small genetic differences exist between the described subspecies.
However, analysing mitochondrial DNA and microsatellites in cheetah samples from most of the historic range of the species we found relatively deep phylogeographic breaks between some of the investigated populations, and most of the methods assessed divergence time estimates predating the postulated bottleneck.
A total of 18 cheetah genes showed damaging mutations and one gene in particular, AKAP4, showed a large number of mutations, which could harm sperm development and may explain why cheetah have a large proportion of defective sperm, and hence their low reproductive success.
