Cryptic evolution
Distributions of related terrestrial and freshwater taxa separated by ocean basins can be explained by either vicariance resulting from continental separation, or oceanic dispersal (i.e., long-distance dispersal across oceans). In the Origin of Species47, Darwin argued that occasional dispersal events—rare but … See more Although alternative views have been proposed28,29, trilobites (probably excluding agnostines30) are now almost universally accepted … See more Trace fossils have also been used to argue for a cryptic history of trilobite evolution. Arthropod traces from the Terreneuvian such as Rusophycus have been attributed to trilobites34 (despite appearing c. 10–15 … See more It has been stated repeatedly that, even in their earliest history, trilobites show marked biogeographic provincialism and phylogenetic diversity4,16,18,19,20,75, being separated into the ‘olenelline’ and ‘redlichiine’ provinces … See more The argument over the importance of vicariance (by continental separation) versus oceanic dispersal in explaining modern biogeographic distributions may be largely irrelevant to the case of trilobites, as this form … See more WebFinding Evolutionary Processes Hidden in Cryptic Species Authors Torsten H Struck 1 , Jeffrey L Feder 2 , Mika Bendiksby 3 , Siri Birkeland 4 , José Cerca 4 , Vladimir I Gusarov 4 , Sonja Kistenich 4 , Karl-Henrik Larsson 4 , Lee Hsiang Liow 5 , Michael D Nowak 4 , Brita Stedje 4 , Lutz Bachmann 4 , Dimitar Dimitrov 6 Affiliations

WebMany authors have suggested that release of this cryptic genetic variation by stressful or novel environments can facilitate phenotypic adaptation. However, there is little empirical evidence that stressful or novel environments release cryptic genetic variation, or that, once released, it contributes to phenotypic evolution.
