Regeneration, the replacement of lost body parts, is widespread yet highly variable among
animals. Explaining this variation remains a major challenge in biology. Great strides have …

Most but not all phyla include examples of species that are able to regenerate large sections
of the body plan. The mechanisms underlying regeneration on this scale are currently being …

The long-awaited revision of the industry standard on phylogenetics Since the publication of
the first edition of this landmark volume more than twenty-five years ago, phylogenetic …

Significant progress has recently been made in our understanding of animal regenerative
biology, spurred on by the use of a wider range of model organisms and an increasing …

With the explosion of knowledge from molecular biology and the burgeoning interest in
generating or regenerating tissues or organs through various bioengineering or stem cell …

Many annelids can regenerate missing body parts or reproduce asexually, generating all
cell types in adult stages. However, the putative adult stem cell populations involved in these …

It has long been recognized that the patterns of growth play an important role in the
evolution of age trajectories of fertility and mortality (Williams, 1957). Life history studies …

The annelids are an excellent group in which to investigate the evolution of regeneration
abilities. They exhibit qualitative and quantitative variation in regeneration ability, including …

Naidids are tiny, primarily freshwater oligochaete annelids which reproduce asexually by
fission. We investigated the phylogenetic relationships within this group by sequencing …

Background The heads of annelids (earthworms, polychaetes, and others) and arthropods
(insects, myriapods, spiders, and others) and the arthropod-related onychophorans (velvet …
