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.
