An analysis of gene dosage at the DNA, RNA and protein level yields new insights into the early stages of Z-chromosome dosage compensation in schistosome parasites.

The insect odorant receptor gene family evolved at the base of the class Insecta before the evolution of flight and perhaps as an adaptation to terrestriality, and was therefore an important evolutionary novelty for insects.

Zebrafish scales depend on interactions among Wnt, Ectodysplasin and Hedgehog signaling pathways similar to those underlying feathers, teeth and hair follicles, suggesting a deep homology of ectodermal appendages in vertebrates.

The expression of 'bilaterian-mesodermal’ genes changes the epithelial properties of the endomesoderm during the embryogenesis of the cnidarian Nematostella vectensis.
The genomes of animal progenitors evolved as mosaics of old, new, rearranged, and repurposed protein domains, genes and pathways and paved the way for the origin and evolution of animals.
New sequence data from choanoflagellates improves our understanding of the genetic changes that occurred along the branch of the evolutionary tree that gave rise to animals.
The symbiotic relationship between Hydra and Chlorella is driven by metabolic co-dependence and characterized by changes in the photobiont genome in terms of lack of genes essential in free-living algae.
Cell biological features are subject to stochastic forces of mutation and random genetic drift, which together cause lineages exposed to identical selection pressures to diverge, and mean phenotypes to deviate from expectations under optimizing selection.
