More than almost any other field in biology, phylogeny, which describes the relationships between different species, is subject to constant redesign and reorganisation. Old phylogenetic paradigms are restructured since researchers more and more draw their conclusions about the degree of relatedness from molecular data like DNA. Especially DNA sequences which show a constant degree of variation within one taxon and between different taxa have been proven to be useful for phylogenetic reconstructions. Such phylogenetic markers can be used to separate different species. Often this approach is...
