Genetic 'remix' key to evolution of bee behavior, researchers find

Worker bees have become a highly skilled work force because the genes that determine their behavior are shuffled frequently, helping natural selection to build a better bee, research suggests. A new study sheds light on how worker bees -- who are sterile -- evolved charismatic and cooperative behaviors. Researchers discovered that the genes associated with worker behavior were found in areas of the genome that have the highest rate of recombination.
