The point of the dataset, which included orangutan sequence, was that  
alignment was NOT hard in that case. Try looking at it. If the  
results from a tree search with this dataset are different than your  
favorite tree (they were in a quick tree search), it is NOT due to  
difficulty in alignment. Thousands of characters recovered without a  
particular tree in mind reject a tree inferred from one particular,  
hand-crafted dataset; one could advance several arguments to justify  
the minority view, but it's a disservice to anyone who reads taxacom  
to continue to advance hand-waving arguments that are demonstrably  
not true.

Just FYI for all: based on quickly grepping the archives, it appears  
that this human-orang discussion has appeared in 32 of the last 54  
months on taxacom. I don't think many minds have changed over that  
time, but I think it's at least worth checking that the arguments  
advanced are potentially valid.
