No it doesn't. Because that would make it even more a fiction of yours.... Something changed into something else a billion and a half years ago. They were quite unlike the protamines and histones of today. What a joke.
Obviously not - we know that histones are highly conserved, but equally obviously your inability to explain why we should expect the same of protoamines is matched only by your inability to faithfully represent the argument you are supposed to be rebutting. Go lie on someone else, or play the fool with someone else, as the case may be - just remind yourself that God loves you for it, and it's all okay.
