Yes, but those informative genes are not likely to carry over from one
problematic group to another. And it will be necessary to distinguish
between-species variation from within-species variation, so the number
of specimens sampled will have to be much higher than is now generally
the case. So it may be a very long time (if ever) before molecular
data proves worth investigating routinely for systematic or taxonomic
problems at this level.
