I actually do have that knowledge, you just speak for yourself. The fact that experts are able to distinguish earlier and later variants doesn't mean that this is trivial, nor does it mean that this is something that is error free. So your statement simply does not stand. Whether or not you can make a statement about the order in which mutations happened (which is the genetic basis for all evolutionary biology) hinges on a large number of factors and not all of those may be in agreement.
I've been somewhat involved in a bunch of issues around determining the sequence in which a plant mutated historically and in spite of a good idea of the overall picture the final call was less solidly supported than the parties involved would have liked. And that's before we get into the thorny issues of gaps in the record and sequence alignment, which by themselves can give rise to all kinds of interpretations.

Yes, I added some more information but the gist of it stands: this isn't trivial. Not by a long shot.
