That is only an assumption that those bones served no purpose.This teaching is based on an assumption that is then is taught as science, the assumption that the ancestry and function of the structure is known. using observational science, it is impossible to identify exact ancestors or even the exact function of structures because observational science deals with things that are observable in the here and now.
You don't understand what you're writing. Vestigial bones suggest remnants of anatomy that were once used and now serve no purpose. Whales, for example,
Why would the gawds add useless parts to humans and animals alike?
No you don't understand these bones assuming they worth left over parts and performed no function is nothing but an assumption and no evidence to back the assumption.
That's a lot of dancing but you're running out of excuses to avoid addressing the issue that the usefulness of vestigial organs / anatomy is assumption.
CB360: Function of vestigial organs.
Practically all "vestigial" organs in man have been shown to have definite uses and not to be vestigial at all.

Response:
1. "Vestigial" does not mean an organ is useless. A vestige is a "trace or visible sign left by something lost or vanished" (G. & C. Merriam 1974, 769). Examples from biology include leg bones in snakes, eye remnants in blind cave fish (Yamamoto and Jeffery 2000), extra toe bones in horses, wing stubs on flightless birds and insects, and molars in vampire bats. Whether these organs have functions is irrelevant. They obviously do not have the function that we expect from such parts in other animals, for which creationists say the parts are "designed."
Vestigial organs are evidence for evolution because we expect evolutionary changes to be imperfect as creatures evolve to adopt new niches. Creationism cannot explain vestigial organs. They are evidence against creationism if the creator follows a basic design principle that form follows function, as H. M. Morris himself expects (1974, 70). They are compatible with creation only if anything and everything is compatible with creation, making creationism useless and unscientific.
2. Some vestigial organs can be determined to be useless if experiments show that organisms with them survive no better than organisms without them.
