Abstract— Our knowledge of fundamental angiosperm interrelationships is still very incomplete. The absence of a narrowly circumscribed gymnosperm outgroup, ideally the sister group, makes character evaluation, necessary for a cladistic analysis, difficult.

Clades Are Reproducers

Biological Theory, 2006
Exploring whether clades can reproduce leads to new perspectives on general accounts of biological development and individuation. Here we apply James Griesemer’s general account of reproduction to clades. Griesemer’s account of reproduction includes a requirement for development, raising the question of whether clades may be meaningfully said to ...

Clade support measures and their adequacy [PDF]

open access: possibleCladistics, 2008
AbstractIn addition to hypothesis optimality, the evaluation of clade (group, edge, split, node) support is an important aspect of phylogenetic analysis. Here we clarify the logical relationship between support and optimality and formulate adequacy conditions for support measures. Support, S, and optimality, O, are both empirical knowledge claims about
