Resumen:
This paper will present an analysis based on the largest phylogenetic dataset ever assembled, consisting of 13 genes and morphology for numerous eukaryotic taxa. The results for the combined dataset recover the existing taxonomy with high accuracy. For the molecule-only dataset, the results present more differences with major taxonomic groupings, but the agreement is still very highly significant. A few misplaced species aside, the molecule-only trees display the bulk of the metazoans, green plants, fungi, red algae, stramenopiles, alveolates, and euglenozoans, in discrete groups. This shows that tree-calculation algorithms can effectively retrieve phylogenetic history for very large datasets, and provides at the same time strong corroboration for the major eukaryotic lineages long recognized by taxonomists on the basis of the morphology alone.
