What is the likely cause for the Cheetah losing genetic diversity?
The cheetah species that survived this period (now known as Acinonyx jubatus) found itself in a genetic bottleneck with only a few animals left. This led to close relatives mating with one another, resulting in genetic inbreeding, which led to the cheetahs losing their genetic diversity as time went by.
What causes population bottleneck?
A population bottleneck is an event that drastically reduces the size of a population. The bottleneck may be caused by various events, such as an environmental disaster, the hunting of a species to the point of extinction, or habitat destruction that results in the deaths of organisms.
Can cheetah populations recover lost genetic diversity?
Cheetahs survived a population collapse more than 12,000 years ago that led to inbreeding and a loss of genetic diversity. They had expected to find that, as a result of their lower genetic diversity, the cheetahs in the wild would have poorer sperm quality than those in zoos.
How has evolution put cheetahs at risk of extinction?
Evolution of Cheetahs
The cheetah species in North America and Europe became extinct, leaving only the Asian and African species of cheetahs. Since then, stress from climate change, habitat loss, and human activities have put pressure on the remaining two species.
