“So what you’re saying...the riddle...has been solved with absolute certainty?”
I’m saying you could answer your own questions if you’d bother to crack a book and do some homework.
Instead, you want to sit in the back of the class and shoot spit-balls at the teacher.

You're insulting, you know that?
You keep throwing textbooks at myself and others without taking any stance on the question at hand, yourself. If you know so much about this subject, why not do the civil thing, and just share what you know in conversation?
This is a discussion forum, not a paleontological symposium.
