Mathematical modeling reveals that haplodiploidy—a genetic system where females develop from fertilized eggs and males from unfertilized ones—provides no evolutionary advantage for developing highly organized social colonies with sterile workers and reproductive queens. The analysis directly contradicts the influential kin selection hypothesis that has dominated evolutionary biology for five decades. This represents a significant paradigm shift in understanding how complex social behaviors emerge in nature. The kin selection theory proposed that haplogiploid species would more readily evolve eusociality because workers share more genetic material with sisters than potential offspring, creating stronger incentives for altruistic behavior. However, comprehensive mathematical frameworks demonstrate this genetic asymmetry fails to provide meaningful selective pressure toward cooperative breeding systems. The findings have profound implications for evolutionary biology, potentially redirecting research toward alternative mechanisms like ecological pressures, developmental constraints, or group-level selection processes. While the study focuses on theoretical models rather than empirical data, it challenges fundamental assumptions about genetic relatedness driving social evolution. This could reshape how researchers approach questions about cooperation, altruism, and the origins of complex societies across multiple taxa.
