A recent study from Arizona State University challenges the long-held belief that haplodiploidy—a genetic system where females have two sets of chromosomes and males have one—is primarily responsible for the evolution of eusociality among insects like ants and bees. An extensive analysis of nearly 69,000 insect species revealed that the association between this genetic system and eusocial behavior is mainly linked to a specific group of insects, particularly the aculeate Hymenoptera. The findings suggest that other environmental factors and life-history traits, rather than genetic inheritance alone, play a significant role in the emergence of complex social structures in these insects. This research provides a critical reevaluation of how we understand the origins of cooperation in insect societies.
