Why do almost all vertebrates have tails, but not apes and frogs?

Vertebrates are chordates and all chordates have, as part of the defining body plan of the phylum, a post anal tail.

And of course, frogs have a perfectly normal and prominent chordate post-anal tail as juveniles.

And apes and frogs are no exception. Both still have the lost anal tail. It is just shortened and entirely hidden inside the adult body. But you can still see it in their skeletons.

What do you think about the NFA full auto band? Weapons built before 1986 can be transferred and registered? But we can't have an 87? But older weapons tend to be far more powerful. I think we should drop it. Input?
