The mitochondrial genome (mtDNA) of Metazoa is a good model system for evolutionary
genomic studies and the availability of more than 1000 sequences provides an almost …

Much of what we know about speciation comes from detailed studies of well‐known model
systems. Although there have been several important syntheses on speciation, few (if any) …

Cephalochordates and tunicates represent the only two groups of invertebrate chordates,
and extant cephalochordates–commonly known as amphioxus or lancelets–are considered …

A combined morphological and genetic study of the coral genus Stylophora investigated
species boundaries in the Gulf of Aden, Yemen. Two mitochondrial regions, including the …

Cephalochordates, the sister group of tunicates plus vertebrates, have been called “living
fossils” due to their resemblance to fossil chordates from Cambrian strata. The genome of …

Marine species are declining at an unprecedented rate, catalyzing many nations to adopt
conservation and management targets within their jurisdictions. However, marine species …

Marine biodiversity reaches its pinnacle in the tropical Indo-Pacific region, with high levels of
both species richness and endemism, especially in coral reef habitats. While this pattern of …

Schindleria (Gobioidei, Schindleriidae), believed to include one of the smallest and
youngest reproducing vertebrates, is broadly distributed in the Indo-Pacific Oceans …

Abstract Background The lancelet Asymmetron inferum (subphylum Cephalochordata) was
recently discovered on the ocean floor off the southwest coast of Japan at a depth of 229 m …

Invertebrates comprise approximately 34 phyla, while vertebrates represent one subphylum
and insects a (very large) class. Thus, the clades excepting vertebrates and insects …
