this is a question in regards to people making Noah-scenario TLs (armageddon, two, or a few people survive).
what would you say is the least amount of people needed to have human kind survive at least a milenium.
i would think that females have to vastly outnumber males (say about 8:1) due to reproductive rates.
i would guess 9000 (8000 female, 1000 male).
