That is the question researchers posed in a new study of the Florida harvester ant, Pogonomyrmex badius, a resilient creature found in many parts of the southeastern United States. The answer? Both nature (i.e. the ant's genetic makeup) and nurture (what it eats, for example) play a role in determining its fate.

New research uncovers the social dynamics of yellow jackets, which includes multiple sex partners, extreme cooperation and a caste system. Results show that multiple mating does not cause conflict within a colony, but instead creates a more successful colony. The researchers also found that certain genes are turned on or off to create the different castes.
