Suppose you did see a small bump on the nose of some creature that may or may not look like a rhino? Are you saying you would know that this small bump will one day be a large horn on its descendants? Do you not have some small bumps on various parts of your body? I know I do. Are you saying these will all turn out to be horns on the bodies of my distant descendants?

I haven’t been following the recent discussion, but what’s the big deal about rhino horns? IIRC they are made of keratin (like fingernails or hair), and it’s no surprise that mammals have hair. WHY such a structure forms on the nose is a better question, but HOW shouldn’t be a big deal.
