So I got into an argument with my dad today. He says that there is way more evidence for intelligent design than for evolution, and that evolution is "just a theory" and has "minimal evidence"
I tried explaining to him, about fossils and genetics but he wouldn't listen
So escapees, most convincing evidence for evolution?
PS: I also tried "Every noteworthy scientist believes in evolution" he just said, no.
For one, gravity is "just a theory," but it certainly exists. A scientific theory is just a model used to explain phenomena. The existence of gravity, evolution, germs, electrons, etc are not in doubt whatsoever. They exist, period, but gravitational theory, evolutionary theory, germ theory, and electron theory are all our explanations, backed up by MOUNTAINS of scientific evidence, to explain how/why these things exist and work.
Next, ask him to point out JUST ONE piece of "evidence" for "intelligent design," and we will summarily destroy it. There is no evidence for intelligent design.
Anyway, to answer your question, appendixes, tailbones, and other vestigial organs/etc, are all evidence for evolution, since plenty of other animals have them as still-functional organs/etc.

Actually, shit, I just searched for "evidence for evolution" expecting the Wiki article but ended up with this next link, which practically mirrors my first paragraph, hah. This is pretty useful, as well as the link afterward:
*EDIT EDIT* This channel has some of the best evidence, explained in very layman's terms, that I have ever seen, and argued in a very well-formulated way:
