Do you think it would be possible, if I handed you three samples of genetic material from my garden, that you might be able to determine which were tomatoes, and which were green beans?
We have a taxonomy not a phylogeny. Assuming I knew the genetic composition of tomatoes and green beans, yes, it's plausible to distinguish between the two.
