Evolutionists have no idea what the platypus and echidna evolved from.
The great platypus and echidna mystery
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. And if the echidna (pronounced ik-KID-na) regards you as a danger, it will probably abandon its meal of ants or termites, roll into a spiky ball, wedge itself into a crack, or rapidly burrow straight into the soil until only its sharp spines are exposed. This gives it excellent protection from almost anyone who doesn't have a shovel to dig it out.
The hedgehog-like echidna is also known as the spiny anteater. It looks nothing like the water-loving platypus (which has a bill like a duck, a tail like a beaver, webbed feet, and soft velvety fur), yet they share one unique feature: they are the only mammals in the world that lay eggs!
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.
Monotremes are a puzzle for scientists who think they evolved. Monotremes are clearly mammals because they have milk glands, hair, a large brain, and a complete diaphragm. Yet they also resemble reptiles and birds in that they lay eggs, their blood temperature is influenced to some extent by their surroundings (as with reptiles), and the platypus's bill is like a duck's.
What on earth could such different animals as the echidna and platypus have evolved from?
The answer is that no one has any idea. 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.
No one has a clue what those mammal-like reptiles could have been, of course, because no “mammal-like reptile” comes close to looking like a common ancestor for the echidna and platypus.
Echidnas and platypuses are unique in their biology, lifestyle, and habitat compared with other mammals, reptiles, and birds. Therefore there is no reason to think that their ancestors were significantly different from today's monotremes.
With no clear evidence from fossils or anywhere else to indicate that echidnas and platypuses have evolved from non-monotremes, it seems more logical to us to deduce that they never evolved at all. We believe that God created them as egg-laying echidnas and platypuses right from the beginning, and they have always been that way.
