Models of Genetic Differentiation and Origin of Troglobites
As for epigean taxa, genetic differentiation is probably more frequently achieved by geographic isolation leading to allopatric speciation of troglobitic species. In view of the vertical spatial continuity, which allows permeability between the epigean and the hypogean compartments of the biosphere and which is higher for smaller organisms, the most plausible mechanism of geographic isolation for most subterranean populations is through local extinction of related epigean populations. A classical model for temperate regions, which also applies to the tropical ones, is based on local extinction due to paleoclimatic fluctuations, rendering the epigean environment unsuitable for many taxa.
