Recent research reveals that breeds such as Persian cats, Pekingese dogs, and pugs have developed strikingly similar skull shapes due to selective breeding for aesthetic traits resembling human babies. This phenomenon, termed convergent evolution, occurs when unrelated species independently evolve similar characteristics in response to the same selective pressures. In this case, the demand for brachycephalic traitsâcharacterized by flat, round facesâis a result of human preferences rather than natural evolutionary processes. Notably, these breeds now exhibit skull morphology more akin to each other than to their wild ancestors, disparaging millions of years of evolution.
Brachycephalic cats and dogs show an unusual example of convergent evolution, evolving to resemble each other due to similar selective pressures for flat, round faces.
Selective breeding for babylike features in pets has led to significant morphological changes, resulting in skull shapes that resemble each other more than their wild ancestors.
