TL;DR: Fossil and subfossil evidence shows that shifts in the ranges of the species have occurred in the late Quaternary; Pleistocene-Holocene environmental changes, habitat destruction by man, and possibly other environmental changes during historical times are probably involved.

TL;DR: Overall, the rDNA molecular phylogeny has remained stable following the incorporation of the additional taxa, with these additions having little impact on the major evolutionary patterns in the tree.
Abstract: We have incorporated an additional 56 species of land snails and slugs in our ribosomal (r) RNA molecular phylogeny The new taxa include representatives of several important groups The molecular tree now includes 160 species of stylommatophoran land snails and slugs in 144 genera in 61 families In the rDNA tree, the Stylommatophora are principally divided into an ‘achatinoid’ and a ‘non-achatinoid’ clade Within these clades, several major land snail groups, including the Orthurethra, Elasmognatha, Limacoidea, and Helicoidea, are supported Overall, the rDNA molecular phylogeny has remained stable following the incorporation of the additional taxa, with these additions having little impact on the major evolutionary patterns in the tree Taxonomic coverage of the Orthurethra, Orthalicidae, Camaenidae, and Bradybaenidae is increased significantly The camaenids and bradybaenids form a complex, and both appear to be paraphyletic Several families of uncertain affinity, such as the Sagdidae and Thyrophorellidae, are included for the first time The Sagdidae are shown to belong to the Helicoidea, and the Thyrophorellidae to the Achatinoidea © 2006 The Linnean Society of London, Biological Journal of the Linnean Society, 2006, 87, 593–610
