how has evolution put cheetahs at risk of extinction?


Organisms that are unable to do this quickly enough can become extinct. A widespread opinion is that conservation efforts disproportionately benefit charismatic species. Cheetahs have long been cited as a classic example of a species whose low genetic diversity put is at increased risk of extinction. While these mass extinctions sometimes wipe out a large majority of life, extinction itself is a continual part of evolution. Today’s modern cheetahs can run 60 mph to catch prey.
