Evolutionary mitogenomics of Chordata: the strange case of ascidians and vertebrates [PDF]
The availability of almost one thousand complete mitochondrial genome (mtDNA) sequences of chordates provides an almost unique opportunity to analyse the evolution of this genome in the phylum Chordata, and to identify possible divergent evolutionary ...

The Spindle Assembly Checkpoint Functions during Early Development in Non-Chordate Embryos
In eukaryotic cells, a spindle assembly checkpoint (SAC) ensures accurate chromosome segregation, by monitoring proper attachment of chromosomes to spindle microtubules and delaying mitotic progression if connections are erroneous or absent.

Echinoderm radial glia in adult cell renewal, indeterminate growth, and regeneration
Echinoderms are a phylum of marine deterostomes with a range of interesting biological features. One remarkable ability is their impressive capacity to regenerate most of their adult tissues, including the central nervous system (CNS).

Evolution of the Chordate Telencephalon [PDF]
The dramatic evolutionary expansion of the neocortex, together with a proliferation of specialized cortical areas, is believed to underlie the emergence of human cognitive abilities. In a broader phylogenetic context, however, neocortex evolution in mammals, including humans, is remarkably conservative, characterized largely by size variations on a ...

Dorsoventral patterning in hemichordates: insights into early chordate evolution. [PDF]
We have compared the dorsoventral development of hemichordates and chordates to deduce the organization of their common ancestor, and hence to identify the evolutionary modifications of the chordate body axis after the lineages split. In the hemichordate

The Hydrocoel and the Ancestry of the Chordates [PDF]
Several traits shared by the tornarian larva of the Enteropneusta and certain larval forms of the Echinodermata, including a transparent body, bilaterality, the arrangement of undulating bands of cilia, and a pelagic existence, are well known to biologists as a whole.
