Cryptic species O could be common in some taxonomic groups, so there might be a lot of biodiversity that has gone unnoticed Oshould be very rare in all taxonomic groups of multicellular organisms given what we know about the evolution of morphology are probably only "cryptic" to us; but recognizable as potential mates for same-species males and females Ohave diverged in outward morphology but not in the ability to exchange genes are ones that mimic other species that are not particularly related to them Oare ones for which there is no impediment that would keep them from coming back together in the future (homogenized by hybridization) 0
