A similarity matrix, with entry (i,j) corresponding to the pairwise similarity between species i and species j. This similarity matrix was derived from a phylogenetic distance matrix, inferred from the tree xue_species_tree, using the expression s(i,j) = exp(-d(i,j)), where d(i,j) is the phylogenetic distance between species i and j.
