Gene Regulation Underlies Evolution of Social Complexity in Bees

Explaining the evolution of insect society, with sterile society members displaying extreme levels of altruism, has long been a major scientific challenge, dating back to Charles Darwin's day. A new genomic study of 10 species of bees representing a spectrum of social living - from solitary bees to those in complex, highly social colonies - offers new insights into the genetic changes that accompany the evolution of bee societies.
