Well, it is relatively accessible, in the sense that the "whatnots" are
being sorted out - it's only a matter of time. Meanwhile, good taxonomic
classifications (when accompanied by detailed group descriptions!) should be
helping point molecular biologists in the right directions for getting
handles on them. In this connection, I can't resist drawing attention to the
fact that the inappropriateness of their term "junk DNA" (belatedly being
debunked) was rather strongly indicated by taxonomic evidence that was
available before the so-called junk was 'discovered'!
