Methods We have sequenced, annotated, and analyzed the 150-megabase genome of the
ctenophore Mnemiopsis leidyi. We have performed detailed phylogenetic analyses on these
new data using both sequence matrices and information on gene content. We conducted
extensive genomic inventories on signaling pathway components and genes known to be
critical to neural and mesodermal cell types, among others. Results Our phylogenetic
analyses suggest that ctenophores are the sister group to the rest of the extant animals. ...
