Dogs have owners; cats have staff. Dogs are man’s best friend; cats are man’s best frenemy. Dogs come when called; cats take a message and get back to you.
As long as we’ve had dogs and cats, we’ve had dogs versus cats. Dogs are obedient, loyal, and love unconditionally. Cats are obstinate, fickle, and love when they feel like it. But are these personality differences rooted in reality—or are they just in our heads?
Science is coming closer to providing an answer.Last month, researchers published the most detailed analysis yet of the cat genome, comparing it to that of the housecat’s immediate ancestor, the Near Eastern wildcat. Among the highlights: several genes linked to fear, memory, and learning that seem to have changed as the cat morphed from feral to friendly. This makes sense, as cats, like other domesticated animals, have had to overcome their fear of humans and adapt to living in our society. We know less about how the dog’s genome changed from that of its ancestor, the gray wolf, but scientists believe it has undergone more—and more intense—genetic changes than that of the cat’s. That’s not a surprise when you consider that cats have only lived with us for about 10,000 years, while dogs have been with us for up to 30,000.
