Figure 1

Stability versus instability of molecular phylogenies (left) and alignments (right): A tree-reconstruction program produces a stable phylogeny if the phylogeny derived for a smaller sequence set coincides with the sub-phylogeny induced, for this smaller set, from the 'complete' phylogeny. Analogously, a multi-alignment program produces a stable alignment if the alignments of smaller sequence sets show the same columns as the corresponding subalignment of the 'complete' alignment.
