So there’s an odd number of each kind of bacteria in the gut?

Also, one bacteria isn’t equal to another of a totally different kind, there’s some that can survive better than others, there’s good and bad bacteria that has a high survivability against the invasions of others.

There’s probably trillions of different kinds of bacteria and each one has its own capabilities…and let’s not forget, they share genetic information with each other all the time.

So after the snap, there’s probably a lot of people who have fucked up gut biomes and other people with extremely healthy ones. Because there’s a different quantity of each kind of bacteria inside of each living thing.

That would probably cause some insane mutations in the next coming months after the snap too. Half the bacteria being gone means there’s 50% less genetic material for them to share.

There’s never an equal number of each bacteria though.
