Helix, you are getting too much propaganda!
Humans do not have, and never have had, tails. The coccyx is a muscle anchor and helps you go to the bathroom! It has nothing to do with a tail. We see this bit of bony structure sticking out in the fetus because the muscle and fat tissue are the last to be added in the course of development. It is not because of any deceitful recapitulation idea, which was disproved long ago.
Nor do whales have legs. They have small bony structures where the pelvis is in most animals with legs. Are these vestigal legs? No, they are small bony structures that help keep the reproductive organs properly situated in the whale's body. Whales undergo massive pressure changes during dives and surfacing and there are elements in their physiologies designed to handle that. Those little bones are part of it.
Whales have always been whales. Anything else is pure imagination based upon the desire to somehow present some kind of evidence that evolution is true.
If you stick to the data -- just the facts -- you will find evolution has nothing to support it.

-- note: just because these bones are called by the names of our leg bones does not mean they are. I can call you a car, but that does not mean you are one!
