Popularity runs in families

To investigate the role genes play in the evolution of social structure, researchers created an experiment they likened to the 1998 film 'The Truman Show.' Genetically identical versions of 20 fruit flies were placed in 98 controlled enclosures, and video cameras recorded their interactions. The study revealed the same clones occupied the same social positions in each enclosure, regardless of living conditions, providing evidence that popularity is heritable.
