That’s not scientific falsification criteria. Try again.
My turn...
1. Several methods of determining phylogenies (ie: Cladistics) are capable of contradicting the existence of evolutionary trees. They could provide counter-evidence for common descent, but they don't.
2. The genetic code could conceivably be different between different groups of organisms. If this happened frequently, it would cause severe problems for the theory of common descent. Instead, only minor differences in the genetic code are found, and they tend to occur in ways that strengthen the evolutionary tree.
3. If there were no significant differences in the fauna at different times, or different geographical locations which have been separated for a very long time from other locations (e.g. Australia), this would be a clear falsification.
4. Not all facts would fit with evolution (e.g. the discovery of a rabbit skeleton in Cambrian shales) and therefore if such facts emerge, evolution would be falsified. It is simply the case that there have not been any facts that have falsified evolution.
5. In order to falsify any scientific theory, one must find a core, lynch pin claim that admits to the possibility of being observably incorrect. Even so, it's not just a matter of finding a single piece of "counter-evidence" -- it may be that what appears at first to be a falsification is a manifestation of a previously unconsidered and unexamined phenomenon. Thus, even if something were found in layer X of some rock, this does not on its face falsify the theory: it must be shown to have no other cogent explanation within the theory it proposes to falsify. Because of this, while it would be somewhat of a chore to falsify evolution's falsifiable claims, it cannot be forgotten that it was an equally difficult chore to construct those conditions that would show it false in the first place, and as such, it would likely take time for the falsification of a theory this encompassing to be accepted as such. The work involved in falsifying any given theory, however, does not go to its falsifiability: just because something is monumentally hard doesn't mean it's impossible.
6. Evolution is falsifiable; it is simply not false.
