Mammals are classified into three main types based on their reproductive methods: monotremes, marsupials, and eutherians. Monotremes, like the platypus, lay eggs and are the most primitive group. Marsupials, such as kangaroos, give birth to underdeveloped young that typically continue to develop in a pouch. Eutherians, or placental mammals, give birth to more fully developed young, supported during gestation by a complex placenta.
