Accepted Answer

Monotremes and marsupials share the characteristic of having some embryonic development outside the uterus. Monotremes lay eggs, and the young continue to develop outside the mother's body. Marsupials give birth to live young that are not fully developed and continue to grow in the mother's pouch.
