TL;DR: A general correlation between molecular divergence and taxonomy is revealed, particularly high for shallow taxonomic levels allowing us to propose a COI universal crustacean threshold to help species delimitation and plead for DNA use in taxonomy.

TL;DR: Recombination is an important evolutionary force in shaping Streptococcus genomes, not only in the acquisition of significant portions of the genome as lineage specific loci, but also in facilitating rapid evolution of the core-genome.

TL;DR: Data suggest that small ranges of macro-stygobionts are the rule, and ranges over 200 km are extremely rare, and a considerable increase in overall diversity at the regional and continental scale and a strong decrease in faunal similarities among regions, coupled with greater endemism.

TL;DR: It is argued that future analyses of evolution and biogeography in subsurface, or more generally in extreme environments, should consider dispersal ability as an evolving trait and morphology as a potentially biased marker.

TL;DR: Analysis of the core genome suggested that among 73 genes present in all isolates of S. mutans but absent in other species of the mutans taxonomic group, the majority can be associated with metabolic processes that could have contributed to the successful adaptation of the species to its new niche, the human mouth, and with the dietary changes that accompanied the onset of human agriculture.
