Dogs Are Becoming Cats? Here's Why Evolution Says Yes

Dogs and cats split from a common ancestor 50 million years ago. So why are some of their most popular breeds starting to share the same face? Evolutionary biologists Dr. Abby Drake (Cornell University) and Dr. Jonathan Losos (Washington University) analyzed nearly 2,800 skulls of dogs, cats, and their wild ancestors, and found something nobody expected: the skull of a Persian cat is now more similar to the skull of a pug than it is to its own ancestor, the African wildcat. The skull of a pug, in turn, is more similar to the Persian than it is to a wolf. Two completely unrelated species, bred independently by people who never consulted each other, arriving at the same face. This is convergent evolution. And we caused it. On purpose. Sort of. The reason, it turns out, comes down to babies, specifically, our ancient, hardwired inability to resist a baby face. Big eyes. Tiny nose. Round cheeks. Evolution spent millions of years making sure we'd find that combination irresistible, so we'd take care of our helpless infants. Then breeders spent two hundred years accidentally applying that same instinct to dogs and cats. The result is a pug. And a Persian. And the uncanny, slightly unsettling fact that they are now, in various ways, basically the same animal. In this episode of Pointe of View, we go deep on the science, the skull morphology, the infant mimicry hypothesis, and the ethics of extreme breeding.
