f humanity ever wants to colonize a planet beyond the solar system, it's going to need a really big spaceship. The founding population of an interstellar colony should consist of 20,000 to 40,000 people, said Cameron Smith, an anthropologist at Portland State University in Oregon. Such a large group would possess a great deal of genetic and demographic diversity, giving the settlement the best chance of survival during the long space voyage and beyond, he explained.

Well When You Put It That Way...
