Uh, this thread got so far off topic that it is hard for you to tell now what it was originally.
The intention was to discuss the problem that some people have with discussing evolution as a theory (how did it happen) and the fact of it happening.
The problem that the non-scientifically aware may have with the scientific meaning of "theory" was the original intent.
So individual facts of the kind you offered up are, IMO, at too low a level of detail to be discussed here.
(at least I think it was ).
