Getting to the bottom of anal evolution
The digestive tract is an essential organ system that allows animals to efficiently digest food and take up nutrients to maintain growth and sustain the body. While some animal groups possess a sack-like gut, others possess ...
Embracing the comparative approach: How robust phylogenies and broader developmental sampling impacts the understanding of nervous system evolution
(The Royal Society Publishing, 2015-11-09)
Molecular biology has provided a rich dataset to develop hypotheses of nervous system evolution. The startling patterning similarities between distantly related animals during the development of their central nervous system ...
The study of Priapulus caudatus reveals conserved molecular patterning underlying different gut morphogenesis in the Ecdysozoa
(BioMed Central, 2015-04-21)
Background The digestive systems of animals can become highly specialized in response to their exploration and occupation of new ecological niches. Although studies on different animals have revealed commonalities in gut ...
Nuclear genomic signals of the “microturbellarian” roots of platyhelminth evolutionary innovation
(eLife Sciences Publications, 2015-03-12)
Flatworms number among the most diverse invertebrate phyla and represent the most biomedically significant branch of the major bilaterian clade Spiralia, but to date, deep evolutionary relationships within this group have ...
Mesodermal gene expression during the embryonic and larval development of the articulate brachiopod Terebratalia transversa
(BioMed Central, 2015-04-11)
Background: Brachiopods undergo radial cleavage, which is distinct from the stereotyped development of closely related spiralian taxa. The mesoderm has been inferred to derive from the archenteron walls following gastrulation, ...
Evolution and development of the adelphophagic, intracapsular Schmidt's larva of the nemertean Lineus ruber
(BioMed Central, 2015-09-28)
Background: The life cycle of many animals includes a larval stage, which has diversified into an astonishing variety of ecological strategies. The Nemertea is a group of spiralians that exhibits a broad diversity of larval ...
