DNA jumps between animal species, but no one knows how often
It's almost unbelievable how DNA seems to "just work". DNA from one organism breaking apart and slipping into another somehow leads to shared expressions across horizontal species - it's absurd.It's like taking a random byte sequence from some binary, shoving it randomly into another, and the new binary gets useful new features.The involvement of even more complex systems like parasites makes it that much more insane to me.
