In fact the article relates that an evolutionary theory has been falsified.Yes, according to the Darwininians, or the more fanatic Darwininianists, it falsifies the other theory not Darwininian evolution. You know, the other theory that does not exist because without Darwininian evolution there is nothing to Biology.
You lost me. Are you claiming that the whole of evolutionary theory (or at least the claim that birds evolved from reptiles) should properly stand or fall on the question of whether rachides or barbs develop (and developed) first? That is an odd and dubious perspective, but it seems the only one under which your posts make sense.
