cheetah stretch before it chases its prey

The evidence of cheetah genetic monotony would only grow. Bob Wayne, a talented postdoctoral fellow in our lab, examined cranial measurements and the bilateral symmetry of cheetah skulls. Although no one is certain why, in most livestock, asymmetry in skeletal characteristics (the difference between right and left measures of a trait) increases with inbreeding. Bob measured sixteen bilateral traits in thirty-three cheetah skulls held in natural history museums in Washington, Chicago, and New York. The study was not perfect because several of the skulls were incomplete due to a bullet hole in the skull. Nonetheless, in nearly every case, cheetah skulls were more asymmetric compared to the skulls of leopards, ocelots, or margays?
