Термиты развили сложное общество благодаря потере многих генов своих предков
Ученые выяснили, что термиты развили сложную социальную организацию не за счет усложнения генома, а напротив, — через потерю множества генов, включая те, что отвечают за конкуренцию сперматозоидов
TL;DR
- Termites achieved complex social organization through gene loss, not genome complexity.
- This gene loss includes genes responsible for sperm competition, suggesting early monogamy.
- Termite genomes are simpler than those of their cockroach ancestors, with lost genes related to metabolism, digestion, and reproduction.
- Resource availability influences the development of termite castes: better-fed larvae become workers, while less-fed ones retain reproductive potential.
- Inbreeding is common in termite colonies when a monarch dies, further strengthening kinship.
- This research provides a comprehensive explanation for the evolution of termites from solitary cockroaches to highly social insects.
