HONEY BEES AS A MODEL ORGANISM Individuals have sophisticated behavioral repertoires + social colony = pretty spectacular phenomena Economically important ($$ for research!) Amenable to experimental manipulation (e.g., worldwide distribution, short lifespans, numerous, movable hives) Research history (life history, evolutionary origins, behavior, physiology, etc.)

HONEY BEES AS A MODEL ORGANISM Ontogeny, behavior, physiology, neurobiology is accessible Honey bee genome is sequenced [ Nature (2006) 43 : 931 949] Evolutionary origins relatively well understood Can test predictions centered on inclusive fitness , evolution of altruism Opportunity to integrate many levels of analysis! Economically important ($$ for research!) Amenable to experimental manipulation (e.g., worldwide distribution, short lifespans, numerous, movable hives) Research history (life history, evolutionary origins, behavior, physiology, etc.) Individuals have sophisticated behavioral repertoires + social colony = pretty spectacular phenomena
