A few [[mammal]]s lay eggs and a lot of them have [[claw]]s. Most mammals bear their young alive, but the egg-laying duck-billed [[platypus]] and spiny anteaters are exceptions. Mammals are different from reptiles in some obvious ways: they have [[hair]] or [[fur]] and produce [[milk]] from mammary glands to feed their young. Mammals are not reptiles.

[[Bird]]s have scales, claws, and they lay eggs. Bird [[feather]]s are modified scales. Bird legs are covered with scales, and their toes have claws. Birds lay shelled eggs, and they are allegedly descendants of small, meat-eating dinosaurs. Scientists who believe in evolution and who classify animals on the basis of ancestry say that birds are reptiles.
