Question

If a mammal gives birth to live animals, how is a monotreme a mammal if it lays eggs? This has been confusing me for the past 30 minutes

Answer 1

Answer:

In some ways, monotremes are very primitive for mammals because, like reptiles and birds, they lay eggs rather than having live birth. In a number of other respects, monotremes are rather derived, having highly modified snouts or beaks, and modern adult monotremes have no teeth.
