Ancient DNA Rewrites Story of Enigmatic ‘American Cheetah’
Ancient DNA analysis has revealed that the extinct animal known as the American cheetah was not actually a cheetah. Findings based on genetic data show the cat lived an Arctic existence in North America. This discovery corrects a long-standing biological classification of the species. While previously identified by physical traits as a cheetah, the genetic evidence proves it belongs to a different lineage. This shift in understanding changes how scientists view ice-age predators in the Western Hemisphere.

DNA Analysis Reclassifies the Extinct American Cheetah
Ancient DNA analysis has revealed that the extinct animal known as the American cheetah was not actually a cheetah. Findings based on genetic data show the cat lived an Arctic existence in North America. This discovery corrects a long-standing biological classification of the species. While previously identified by physical traits as a cheetah, the genetic evidence proves it belongs to a different lineage. This shift in understanding changes how scientists view ice-age predators in the Western Hemisphere.
Why it matters
The American cheetah was a prehistoric predator whose identity remained debated for years. This reclassification clarifies the evolutionary history of cats in North America. It helps researchers understand how extinct species adapted to extreme environments.
What is confirmed
- Ancient DNA reveals the extinct American cheetah was not actually a cheetah.
- The extinct North American cat lived an Arctic life.
Still unconfirmed
- Bones found in the Yukon were identified as an ice-age cheetah.
What to watch next
- Further genetic comparisons with other extinct feline species
- Identification of the specific feline lineage the American cheetah belongs to
