America bottleneck cheetah dating genetic

Speculators suggest that these three cats could have co-existed in a way similar to what the cheetah, leopard, and lion do in Africa today.

Trumani is recent history by comparison, dating back to as late as only twenty thousand years ago.

The bones are the remains of the giant cheetah, Acinonyx pardinensis.

The giant cheetah was as tall as a modern lion, but not nearly as bulky as a lion.

Smaller cheetah fossils found in southern and eastern Africa date back to nearly the same time period.

This situation could be similar to the tiger today, where we find a variety of tiger subspecies that vary significantly in size and coat type.

The rumor mill tells of a third lesser known cat called Miracinonyx studeri which lived in North America at the same time as Truman, but details are thin.

Or on the other hand, its extinction might have cleared the way for these other cats to move in from elsewhere.

Slightly later in time we see another variety called Acinonyx intermedius, which was smaller than the giant cheetah, but still larger than the African cheetah.



This research, done by an international team and published in Genome Biology, uses whole-genome sequencing to establish not one, but two major bottlenecks in the cheetahs' history. The first, dating to around 100,000 years ago, came when a small founder population of cheetahs broke away from American pumas and.… continue reading »

By analyzing the few variations in cheetah DNA, O'Brien and Wildt determined that cheetahs had passed through a population “bottleneck” about 12,000 years ago. Some apocalyptic event had wiped out all but a few animals that then interbred, with disastrous consequences for the animal's gene pool. The obvious culprit.… continue reading »

North American has hosted at least two cheetah-like cats Miracinonyx inexpectatus and Miracinonyx trumani. The rumor mill. Inexpectatus is much older, with fossils dating back to over two million years ago. Cheetahs are infamous for their lack of genetic diversity, meaning that they are all closely related to each other.… continue reading »
