Deuterostomes are the major division of animal life which includes sea stars, acorn worms,
and humans, among a wide variety of ecologically and morphologically disparate taxa …

Cnidarians are fascinating creatures at the base of metazoan evolution possessing an
almost unlimited regeneration capacity that has attracted the interest of researchers, from …

Molluscs comprise the second largest phylum of animals (after arthropods), occurring in
virtually all habitats. Some are commercially important, a few are pests and some carry …

The Cambrian explosion was a unique animal radiation~ 540 million years ago that
produced the full range of body plans across bilaterians. The genetic mechanisms …

While components of the pathway that establishes left-right asymmetry have been identified
in diverse animals, from vertebrates to flies, it is striking that the genes involved in the first …

Temporal collinearity is often considered the main force preserving Hox gene clusters in
animal genomes. Studies that combine genomic and gene expression data are scarce …

Transforming growth factor β (TGF-β) signaling controls diverse cellular processes during
embryogenesis as well as in mature tissues of multicellular animals. Here we carried out a …

Many bilaterally symmetrical animals develop genetically programmed left–right
asymmetries. In vertebrates, this process is under the control of Nodal signaling, which is …

Snails, earthworms and flatworms are remarkably different animals, but they all exhibit a
very similar mode of early embryogenesis: spiral cleavage. This is one of the most …

The" Spiralia" represent one of the three major clades of bilaterian metazoans. Though
members of this clade exhibit tremendous diversity in terms of their larval and adult body …
