Is there any actual evedence that Trayvon assaulted George Zimmerman?
Like I said in an earlier post* I believe you are leaving off an implied qualifier.
The answer to your question:
Is there any actual evidence that Trayvon assaulted George Zimmerman?
Is yes, we can be almost 100% sure of that. There is very solid evidence that M assaulted Z.
On the other hand if you meant:
Is there any actual evidence that Trayvon assaulted George Zimmerman
first?
The answer is basically no. No solid evidence has been released so far that shows who initiated the fight.

Well, if it is to be relevant, your question should read: What evidence is consistent with Zimmerman attacking Martin first?
The answer would be none.
As you word it: "What evidence is consistent with Zimmerman attacking Martin?"
The answer would be not much. Martin was very nearly unscathed in the fight until a weapon was used.
Likewise if you asked: "What evidence is consistent with Martin attacking Zimmerman?"
The answer would be plenty. Zimmerman is quite beat up.
But if again, and most relevant to the case, if you word it with the important qualifying word at the end: "What evidence is consistent with Martin attacking Zimmerman first?"
The answer would be: All we have is Zimmerman's word, which has been shown to be quite unreliable, especially on Friday.
Aside from Zimmerman's word there isn't relay any solid evidence of who attacked whom first.
Since, as far as we know, there were no witnesses to that crucial minute or so, there may never be any evidence towards who attacked whom first.
