I'd guess you need to look at the the morphology in juveniles, as well as
juveniles in 'genetically prognathic' earlier species. If the juveniles in
the earlier species are prognathic from a very young age, then you would
know that so should Neandertals, *if* it was a genetic designation.
However, if the prognathism doesn't develop until, say, midl-to-late
teens, that would be a better indicator, I should think.
