The marine bacteria traveled on the seaweed into human digestive systems, where the crucial genes were transferred to bacteria in the gut.
I wonder if this really translates to Japanese people being able to eat more sushi than Americans can, as this article
suggests. I certainly remember chomping on packets of seaweed for snacks when I was a kid — do you know any non-Japanese people who did the same and were not able to stomach it?
