I can’t remember where I read this, but if carefully managed, humanity, in a highly controlled environment, could start off with as little as around 36 individuals. But population and reproduction would have to be highly controlled for dozens of generations before we could breed freely. this is all purely from a genetic standpoint.
And, of course, we would have to be in an environment where we wouldn’t worry about food or pathogens or predators, or anything else that might be a threat to our survival— including each other, or, possibly, ourselves.
The comment you were responding to is estimating a necessary population that takes into account a lot of other environmental factors.
