I am planning on writing a story/book and the idea I've got comes from other books I've read that start with a similar premise, never take where I'm thinking. I was wondering if it was possible to have lets say about seven women and one man, isolated from anyone else start a viable population that will last. If possible how would they go about doing that.
If you want bonus points from me the other idea I had for this group was an outside force that causes there to be an only 1/4s chance of conceiving a male child.
