Families Might Make the Best Spacefarers

According to John Moore, a University of Florida anthropologist, families might have the right social dynamic to take on long duration space voyages - such as the colonization of another star, which could take 200 years to reach. By organizing the crew along family lines, Moore believes a crew would be better protected from problems that could occur over a multigenerational journey. In fact, in order to have enough genetic diversity to seed a new plant, Moore believes you only need a starting population of 150-180 people.
