The DNA analysys for sibling species is best done with mitocondrial DNA as
it changes faster..
AS you will know, most DNA is silent (has no know biological function) and
so you can compare mtDNA in the same silent gap for many related species. It
is an oversimplification to say that <x% difference - same species, >x%
different species, but that is the rough idea.

At the risk of getting too technical, how does DNA evidence prove/disprove
whether or not they are the same species? Given that DNA is just a sequence
of genes do they just draw a line 40 genes along the sequence and declare
"if it's the same to here they are the same species". DNA or otherwise,
isn't species level classification a biological construct based on grouping
similarities?
