The platypus is a great example for showing that evolution does explain the world.
Most mammals give live birth. But mammals evolved from animals that laid eggs. We wouldn't expect to see creatures evolve immediately from hairless egglayers to hairy creatures that give birth to live babies. We would expect to see gradual changes. We would expect to see early mammals lay eggs, but grow hair. At one point there were probably a lot of species of mammals that laid eggs. However, in most places, they would die out because egg layers are at a disadvantage. Birds are able to fly someplace safe to lay eggs -- but mammals who lay eggs would die out quickly because of predators.
Australia was a place where one species of egg laying mammal could survive -- because the platypus doesn't hav natural enemies. The next phase of the evolutionary trail would be what happens with marsupials. This is about half way between egg-laying and the live birth of most mammals. It is no accident that Australia is home to the greatest varieity of marsupials. Being cut off from other continents, they were allowed to evolve without man or other predatory mammals killing them.
There are other egg-laying mammals that still exist. There are four species of ant-eaters that are also found in Australia and New Guinea.
We get more evidence of evolution when we look in the oceans. There are fish that lay eggs, but there are also fish that have live births. The ones that lay eggs are usually primative in many ways, while the ones that have live births have evolved in other ways as well.
I've really only addressed the egg-laying of the platypus. But the other features that you mention are also evidence of evolution. The webbed feet is an obvious sign of natural selection. Early playtpus without webbed feet would have an obvious disadvantage compared to those who developed webbed feet. The ones with the advantage would survive -- and they did.

Monotremes (like the platypus and the echidna) appear to be the surviving branch of early mammals. They are warm-blooded, produce milk, and have fur, but they represent a mammalian branch that did not go on to producing live young (as did the marsupials and placental mammals).
The leathery snout of a platypus, while at a distance resembling a duck's bill, upon closer examination ends up very different in both structure and make-up. The platypus uses its sensitive snout to search for food.
Webbed feet have evolved in several different water-dwelling species, including beavers and muskrats, it's competitive evolutionary advantage being fairly obvious to see.
Your question suggests that there is no evolutionary explanation for the existence of this creature. Its presence (and that of the other monotremes) on the planet is actually a wondrously lucky example of evolutionary branching during the early stages of development of mammals.

Sinyckel is correct. The answer he's looking for is this:
You can't! It can't be explianed via evolution! This is why evolution is false and darwin was a racist ignorant who recanted on his deathbed! The only explanation for the platypus is God! Read it in drdino.com and answersingenesis.com!
Randomly capitalise words here and there in that paragraph as necessary.

Are you seriously asking this question? As an evolutionist I do not claim to have all the answers...I, unlike you, am open to new ideas and widely accept and admit that there are things I do not know. And even if I knew the EXACT answer to your question, I would not give it. You would simply bash it and ignore it. Do not ask questions out of spite...that just shows ignorance and well...impoliteness.

This is what you are likely to get.If you read it though it gives no explanation only a surface argument against creationists.And the over emphasis on the fossil being totally different(it had teeth as an adult where modern form loses teeth at adulthood).

Go take a college level course in evolutionary biology and stop asking silly questions that simply display your silly ignorance.

how about evolutionists stop being close-minded and try to maybe grasp the idea of possibly a higher power than them.
