Experience should be a caution against writing off any part of the human body as useless or junk.

I agree, and I'll go further. I was incautious to imply the issue is settled.

I will say that a lot of work has been done on junk DNA, and more is being done.

However, there isn't much doubt that most of it is derived from an evolutionary past, and much of it was directly useful -- coding --in former times.

However, there isn't much doubt that most of it is derived from an evolutionary past, and much of it was directly useful -- coding --in former times.

And isn't some of it evolutionary leftovers that no longer does what it was originally useful for but has been commandeered by the genome to do something else? I.e., repurposed junk? Or am I confusing two different things?

Well, yes, as a person believing evolution to be fact you see these genes as consistent with an evolutionary past just as a creationist would say, ‘This is evidence of God’s work’,
I lean toward the idea that’s nothing’s useless on the human body. Like all the parts of a well engineered machine,
some parts may be removed without stopping the machine but every part contributes to it’s functioning at the highest level possible.
I look forward to what might be learned.
