One of these 6 pairs is even more ancient, a conserved pairing from
nematodes thru humans. It is known as such within the vertebrates, but
so far I've not found a paper that has identified this much more
ancient pairing. In all genomes, the pairing is reverse tandem
(5'-5'). Expression is strongest in embryos for both genes (in
drosmel, daphnia, and worm), dropping off in adults. Does this whet
anyone's appetite to help write a simple paper?
Of the other 5, one may be conserved outside arthropods, but not as
broadly. A few others are not apparently conserved grouping outside
arthropods, but one pair seems to have one ortholog in nematodes, the
other's best match is in humans with no obvious nematode ortholog.
