We essentially found a similar situation when some "junk" DNA of humans and mice were identical(humans, mice, and the common ancestor lie in the same strata). There is no reason for that situation to have occurred according to Darwin's theory.

Odd, I don't recall Darwin commenting on the mechanisms of DNA replication, nor on the probabilities of accurate replication in the absense of obvious selection.

I'm kind of curious about what ID says about this. Since replication errors occur, and this fact is not in dispute, how does ID explain long sequences replicated without error.

It would seem to me that there are several possibilities: the sequence has a yet unknown function that is being selected; the sequence is at the extreme end of a bell curve distribution of preserved sequences; it's a miracle.

I'm curious. Is there a nice curve published somewhere of preserved sequence lengths?

We've gone over this before. Look at Blast and use the numbers it gives you to your hearts content.
