Termites construct thermoregulating homes that can dominate the landscape, and that are inspiring new energy-efficient skyscraper designs. The organization and collective decision making of eusocial insects is even yielding new insights into human behavior and what it means to be part of a society. But one of the biggest unanswered questions in our understanding of these complex insect groups is how a single genome can produce such diverse and contrasting physical and behavioral forms, from egg ...
