Are there useless body parts and do they prove evolution?

Body parts like tonsils and the appendix were once considered unnecessary organs left over from evolution. But scientists have discovered that these “unnecessary” organs are actually very useful.

Number one: vestigial organs. In 1865 a German anatomist named Robert Weidersheim said that he discovered 185 different useless or virtually useless organs in the body. And he said this was evidence of evolution. In fact the argument goes that if humans evolved then they would have had at one time organs that an animal would have used in a certain way but would no longer be used in that way in the human body. And those organs would begin to atrophy and start to be useless. The problem with this vestigial organ idea is that there are two reasons it cannot prove evolution.

Number one: if you did have vestigial organs in your body, that wouldn’t prove evolution. You see evolution has to go from a single-cell organism to a human and you don’t need organs that are decaying and atrophying. You need evolution to produce new organs. We should find wings that are almost ready to allow organisms to fly that can’t yet fly. We should find new visionary optical connections in living organisms that don’t have them. We should see things adding information, not losing genetic information.

And the second problem with the vestigial organ argument is that that 185 list of vestigial organs, it began to dwindle very rapidly when we started looking more closely into them and it became 180 and then 175 and then do you know as we look more into the body we realize that those vestigial organs were very useful, many of them extremely useful.
