Australia's platyuses and echidnas haven't evolved Evolutionists have no idea what the platypus and echidna evolved from. If you walk through the Australian countryside and see what looks like a wire brush stuck in an ants' nest, it may be an echidna having a snack. This gives it excellent protection from almost anyone who doesn't have a shovel to dig it out. All other mammals known give birth to live young. This has led to the classification of the echidna and platypus in a distinct scientific category known as the monotremes.
Monotremes have a single opening for their digestive and genital organs.
Scientific puzzle Monotremes are a scientific puzzle if you are an evolutionist. They are clearly mammals because they have milk glands, hair, a large brain, and a complete diaphragm. The oldest monotreme fossils show little difference from today's animals, so there is no fossil record to indicate they have evolved from any other type of creature. Evolutionary ancestry is unexplainable Because the monotremes are so different from other mammals, most evolutionary authorities realize that the alleged evolutionary ancestry of echidnas and platypuses is unexplainable. All they have come up with by way of a suggested explanation is that the monotremes must have originated from a line of mammal-like reptiles different from that which gave rise to the other mammals.
