You countered "Why does "fitness" imply one and only one specific function?" with "How do you drive a single car down two different roads at the same time?"

It appears this was a foolish analogy, since clearly fitness does imply more than one specific function.

Well, you didn't read the rest of the discussion, because I answered that. post 53--- Only if the car is not required at the original destination.

As I've pointed out before, "If you're going to make an analogy, make sure it's a valid comparison". Oddly enough, that seems to enrage at least one of the participants of this thread, which perhaps is why he doesn't take the advice and continues to repeat this mistake.
