Abstract The live phylogeny problem generalizes the phylogeny problem while admitting the existence of living ancestors among the taxonomic objects. This problem suits the case of fast-evolving species, like virus, and the construction of phylogenies for nonbiological objects like documents, images, and database records.

The three genera traditionally classified as Pilobolaceae have been identified on the basis of morphological characteristics. In the absence of distinctive morphological differences phylogenetic techniques have proven to be superior for developing phylogenies.

When I have the opportunity to watch a bright young surgeon just a few years out of medical school as he casually stops his patient's heart and proceeds confidently with barely imaginable technical procedures while the patient's physiology is totally dependent on iatrogenic support, I feel like Darwin did as he looked at dinosaur bones in Patagonia ...

The genus Yucca is widely recognized for its pollination mutualism with yucca moths. Analysis of diversification in this interaction has been hampered by the lack of a robust phylogeny for the genus. Here we attempt the first extensive nuclear DNA based assessment of the phylogenetic relationships of Yucca. We used AFLP markers to recover the phylogeny

• Premise of the study: The Lamiidae, a clade composed of approximately 15% of all flowering plants, consists of five orders: Boraginales, Gentianales, Garryales, Lamiales, and Solanales; and four families unplaced in an order: Icacinaceae, Metteniusiaceae, Oncothecaceae, and Vahliaceae.

Diatoms are among the most diverse groups of eukaryotic microorganisms and there are probably well in excess of 100,000 species (Mann and Droop 1996).The beauty and unbelievable variation of their intricately shaped and ornamented silica cell wall, called the frustule, have attracted taxonomists and naturalists alike (Round et al. 1990). More recently,

For the first time a single experimental approach, 16 S ribosomal RNA sequence characterization, has been used to develop an overview of phylogenetic relationships in the bacterial world. The technique permits the tracing of relationships back to the common ancestor of all extant life.

Publisher Summary This chapter discusses the phylogeny of immunoglobulins. The chapter offers a definitive review of the immunoglobulins of various species. The chapter provides the phylogenetic tree based data that are used as a perspective for the understanding of the development and present structure of the complex immunoglobulin systems of man ...

▪ Abstract The vitality of the phylogenetic dialogue in trichopterology, especially since 1967, is evidenced by the high quality and large number of published phylogenetic inferences concerning caddisflies and the continuing spirited exchange of opinions about some differences among those ideas. Monophyly for Trichoptera seems well argued.
