"Yes, you do. Science is not art or literature, where matters of opinion and interpretation count."
Really?
So there is no interpretation or opinion involved when deciding where fossils belong in the evolutionary tree?

If that's the case then there would be no difference of opinion among scientists and no need to revise parts of the tree from time to time.
