Do any mammals lay eggs?
The duck-billed platypus and the spiny anteater lay eggs. They are determined in Australia, Tasmania and New Guinea. They were among the first mammals on Earth. Apart from laying eggs, they are comparable to other mammals. They are warm-blooded, have hair and produce milk to feed their young. But neither anteaters nor platypuses have any teeth. They have snouts that seem to be like beaks.
