You’re asking me to do what, exactly? Create a data matrix of cars and trucks, analyze it, and show that it isn’t a nested hierarchy? No, the burden is on you to show that it is. I’d say that it’s obvious.
No, I said no such thing. I said that if such a thing happened, that would not cause a problem for an evolutionary explanation for everything else, because it would be a one-time magic trick unrelated to how anything in the world actually works. You are very, very confused.
