Inferring evolutionary relationships from DNA or protein sequence data is now routine in biological investigations. Although techniques have improved for using such information to generate phylogenetic trees that represent these histories (1), challenges remain. In particular, the computational demands of preferred statistical approaches make them infeasible for finding large phylogenies. However, on page 1376 of this issue (2), Roch theorizes that a less comprehensive analysis might be surprisingly reliable.
