Two bee studies

The first In Bees, a Hunt for the Roots of Social Behaviour describes studies of the genome level differences between solitary and social bees as well as diferences between social bees engaged in different tasks. One species 'sweat bees' has both behaviours depending on the region they come from. The second No Glass Ceiling for Worker Bees describes what happens in a hive of honey bees when elite foraging bees which do hlf the work are removed "Then, by removing those top performers, the team found that other bees took their place. It was, said Dr. Robinson, “elitism with a populist streak.”"
