In figuring out the family tree of phylogenetic relationships within any group of organisms, features that are constant within that group or that are inherited from its last common ancestor are of no help. The only useful evidence comprises evolutionary novelties that have appeared within the group...
The character × taxon matrix supplies the data for constructing aphylogenetic treeor cladogram. For example,Figure 2.6illustrates construction of the cladogram for the five species of the hypothetical genusXidfrom the character × taxon matrix atFigure 2.6A,B. First, the OTUs are grouped togethe...

If synapomorphy and monophyly were equivalent, phylogenetic systematists should find a single tree, instead of multiple equally parsimonious trees. Understanding synapomorphy as the relevant evidence for phylogenetic inference reveals a category mistake in contemporary phylogenetics: the treatment of ...

Synapomorphy provides the empirical evidence for monophyly, inferred from character analysis in the context of a three-taxon statement. If synapomorphy and monophyly were equivalent, phylogenetic systematists should find a single tree, instead of multiple equally parsimonious trees. Understanding synapo...
