Humanity traveled the world throughout its history, creating colonies and cities–for better or worse. If we are to travel through space to other planets, we might need to consider lessons from our past.
Their paper, which is published in Acta Astronautica, uses island archaeology to outline eight different lessons that can impact the success of ongoing space colonization efforts. Considerations for space colonization go beyond just the technical abilities to live on the surface of another world—they have to consider resource availability, genetics, and cultural ties as well.
The authors split the eight lessons into two main categories—physiological factors and biocultural factors. Their first lesson is that distance is important—no surprise there really. Colonization of other islands is most successful when they are close to their source population. This allows help to arrive faster if needed, but also allows the colony‘s population to be part of a “metapopulation” with the source population.
