When social animals are separated from their colony and placed into isolation, their lifespan is reduced, a study finds.
In 1944, two French entomologists -- Pierre Paul Grasse and Remy Chauvin -- separated small groups of social insects (between 1 and 10 bees) from their colony to measure their respective life span. They found that groups of 10 individuals lived longer than groups of 1 or 2 individuals. This suggested that the lifespan of individuals may be affected by their interaction with the group to which they belong.
