Glossary of terms used in Phylogeny Reconstruction.
is a method based on the analysis of quartets of sequences. The best
four-taxon tree is constructed from every possible combination in a dataset.
Then a 'puzzling' step is used in order to construct a tree from the complete
dataset. The final tree is a heuristic
approximation. On the internal nodes it is possible to place values
from the puzzling step, which indicate the number of times it appeared
during the puzzling process. These values have been shown to be very
close to bootstrap values, at least
for a few datasets.
