      I don’t think the bare minimum of people creating a self-sustaining population can afford to be monogamous. Though it doesn’t take many generations before that can start, 2nd gen might even be able to, assuming 1st gen has enough kids.

    I remember reading somewhere it was around 500-1000 for a sustainable human colony to begin. Did we get better at avoiding Hapsburg Jaws?

      I was wondering the same thing before reading the article. This is for a 28 year mission, and doesn’t include setting up the base, or power and water supply.

      I think that number comes from long term genetic diversity issues. Some rule in biology about inbreeding depression came up with it

      If it’s basic generic viability I’ve always heard 30-60 though I couldn’t name a source for that.

      I’m sure the “computer-savvy” nephew that came along to the colony can do the designer’s work, a lot cheaper too

    And then you wonder why it specifically states “no more…no less …”

    Does playing RimWorld count as running a simulation? Cause managing 22 people is too much trouble, unless a few might just be there in case the crops don’t do well.

      Iirc, the Matrix used that same number for determining how many humans to leave alive outside of the matrix so that the community wound be self-sustaining before they were able to ramp up breaking people out again.
