Pokemon Origin Crisis Lead
I feel I must point out that it sort of doesn't really make sense for DNA to fall from the sky. DNA is microscopic; even if it COULD fall, no one would ever know. It would be more logical if they discovered something that the DNA was on, whether that be a rock or an artifact or mysterious space debris or some piece of an organism [from the digital world] that they don't recognize as such because it's unknown to science...Whatever your decision, finding a single strand of DNA by itself is virtually impossible. This also applies to the disappearing trainers.
