Cat DNA is much more similar to dog DNA than to tortoise DNA. Why? (a) Cats and dogs are both carnivores and take in similar nutrients. (b) Cats and dogs have lived together with humans for a long period of time, so they have grown more similar. (c) Cats and dogs have more offspring during their lifetime than tortoises have, so their DNA changes less rapidly. (d) Cats and dogs have a common ancestor that is more recent than the common ancestor of cats and tortoises.
