The new whale shark genome assembly represents the best gapless chondrichthyan genome assembly yet, and comparative genomic analyses provide insights into the evolution of vertebrate genome origins, immunity, and gigantism.

A fatty acyl reductase gene family expansion in the Hymenoptera crown group led to recruitment of novel pheromone-biosynthetic enzymes and is linked to evolution of pheromone marking behavior.

Rapid evolution and gene conversion of a primate cell surface receptor family blocks recognition by pathogenic bacteria.

A nightshade family gene cluster creates phenotypic novelty in trichome defensive metabolites via evolution of lipid metabolic enzymes.

The foundations of genomic complexity in multicellular animals have deep roots in their unicellular prehistory, both in terms of innovations in gene content, as well as the evolutionary dynamics of genome architecture.

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.

Ancient evolutionary signatures reveal mechanistic details of substrate specificity in copper-transporting mitochondria carrier family proteins.

Sox21b-1 regulates simultaneous formation of anterior segments and addition of posterior segments in a spider, which resembles segmentation in long- and short-germ insects, and suggests SoxB regulation of segmentation is an ancestral feature of arthropods.

In-silico modeling of gene and protein emergence reveals how colony-stimulating factors contributed to the evolution and functional adaptions observed in mammalian neutrophils.
