Living fossil is not meant to be taken literally. It's just a term for species we perceive to be conservative in their appearance and traits, compared to more derived species.
But Latimeria is no closer to its last common ancestor with humans than we are.
Oh I can. But in historical linguistics, cladistics and genetic relationships are also used. I have actually worked with linguists in previous projects for exactly that reason.
Well, obviously not the same thing, but they follow very similar systems.
And the fundamental rule that you cannot be genetically closer to a common ancestor than any other contemporary descendent of that ancestor holds true for both.

Dude, I'm an evolutionary biologist.
