TL;DR: Overall, gene repertoires suggest that the route to advanced eusociality in bees was mediated by many small changes in many genes and processes, and not by notable expansion or depauperation.

TL;DR: The phylogenetic position of myriapods allows us to identify where in arthropod phylogeny several particular molecular mechanisms and traits emerged, and concludes that juvenile hormone signalling evolved with the emergence of the exoskeleton in the arthropods and that RR-1 containing cuticle proteins evolved in the lineage leading to Mandibulata.

TL;DR: This work reviews recent data from a range of arthropods, identifying which features of the D. melanogaster segmentation cascade are present in the different groups, and discusses the evolutionary implications of their conserved and divergent aspects.

TL;DR: These analyses demonstrate how large-scale comparative genomics can provide broad new insights into the genotype to phenotype map and generate testable hypotheses about the evolution of animal diversity.

TL;DR: The expression of two genes, an odd-skipped related gene (odr1) and a caudal homolog, that serve as markers for early steps of segment formation in the geophilomorph centipede, Strigamia maritima, provide the first clues about the causality of the unique and fascinating "all-odd" pattern of variation in centipedes segment numbers.
