Animals commonly called reptiles, amphibians, birds, and mammals are all tetrapods—a term that means “four feet.” The transition from water to land is fascinating to scientists in part because it’s our history—the transition documents the evolution of tetrapods, and humans are tetrapods. Tetrapods form a clade. Which of the following is true of tetrapods?
Tetrapods are more complex than non-tetrapods.
Tetrapods are more evolved than non-tetrapods.
Tetrapods are more closely related to each other than to non-tetrapods.
All of these are true.
