This study investigates the molecular evolution of sociality in weevils, finding relaxed selection and gene loss rather than adaptive innovation in socially complex species.

This study compares regulatory changes in transcription factors during the social transition from cockroaches to termites, finding reduced regulatory complexity despite similarities with Hymenoptera.

This study analyzes weevil genomes to understand the molecular mechanisms of parental care evolution, finding convergent gene loss and regulatory changes associated with subsocial behavior.

This study links rapid termite diversification to increased transposable element activity across two evolutionary waves.

The paper presents two new high-quality genomes from the cockroach genus Cryptocercus to study adaptations to xylophagy and subsociality, finding relaxed selection and positive selection in energy production pathways.

This study investigates the evolution of sex determination in termites using genome assemblies, finding undifferentiated sex chromosomes and varying roles of the doublesex gene.

The paper identifies genetic changes in odorant receptors and other genes associated with termite sociality across multiple species.

This study sequenced 47 termite genomes, revealing genomic expansions linked to dietary evolution and ecological success in Termitidae.

This study identifies convergent genomic changes in socially parasitic ants, showing gene loss, innovation, and network rewiring in parasites compared to hosts.

The paper identifies common genomic pathways involved in viviparity across insects, suggesting convergent evolution mechanisms shared with vertebrates.

The paper investigates molecular mechanisms of longevity in termite reproductives, finding upregulated IIS pathway genes without fat accumulation.

This study examines immune gene diversity and activity in termites and cockroaches, finding reduced diversity and caste-specific defense systems in termites.
