REP provides meaningful measurement of support across datasets.
Clade support measures and their adequacy
  • Taran Grant, A. Kluge
  • Psychology
    Cladistics : the international journal of the Willi Hennig Society
  • 2008
TLDR
The logical relationship between support and optimality is clarified and adequacy conditions for support measures are formulated and it is confirmed that the relative fit difference (RFD; relative GB support) nor any of the parsimony or statistical support measures based on clade frequencies satisfy the adequacy condition.
The limits of understanding in biological systematics
TLDR
The pursuit of ultimate understanding by way of spurious procedures such as contrived testing, Bremer support, and resampling methods are discussed with regard to phylogenetic hypotheses.
Is REP a measure of “objective support”?
  • J. Farris, P. Goloboff
  • Philosophy
    Cladistics : the international journal of the Willi Hennig Society
  • 2008
TLDR
This paper discusses Grant and Kluge's claim that Bremer support and their own REP (“relative explanatory power”), are the only objective measures of group support, showing that their philosophical arguments have no basis, and that their own numerical examples actually serve to illustrate shortcomings of REP.
Explanation and Falsification in Phylogenetic Inference: Exercises in Popperian Philosophy
  • A. Kluge
  • Philosophy
    Acta biotheoretica
  • 2009
Deduction leads to causal explanation in phylogenetic inference when the evidence, the systematic character, is conceptualized as a transformation series. Also, the deductive entailment of
Exploring the impact of morphology, multiple sequence alignment and choice of optimality criteria in phylogenetic inference: a case study with the Neotropical orb-weaving spider genus Wagneriana (Araneae: Araneidae)
TLDR
A total evidence phylogenetic analysis of the Neotropical orb-weaving spider genus Wagneriana is presented and the phylogenetic impacts of methodological choices are discussed.
The nature of parsimony and instrumentalism in systematics
TLDR
It is argued that phylogeny reconstruction looks back to the empiricist tradition in its application of parsimony, and the radical coherentism that motivates the application of Parsimony in direct optimization of sequence alignment results in an instrumentalist approach to phylogeny reconstructing.
Re-writing Popper's philosophy of science for systematics.
  • O. Rieppel
  • Philosophy
    History and philosophy of the life sciences
  • 2008
TLDR
The use of Popper's philosophy of science by cladists in their battle against evolutionary and numerical taxonomy is explored.
Phylogeny of Riama (Squamata: Gymnophthalmidae), impact of phenotypic evidence on molecular datasets, and the origin of the Sierra Nevada de Santa Marta endemic fauna
TLDR
Analysis of character evolution indicates that the presence/absence of prefrontals is optimally explained as having been plesiomorphically present in the most recent common ancestor of Cercosaurinae and lost in that of the immediately less inclusive clade, and proposes a monophyletic taxonomy that reflects historical relationships.
Systematics of the Neotropical Genus Leptodactylus Fitzinger, 1826 (Anura: Leptodactylidae): Phylogeny, the Relevance of Non-molecular Evidence, and Species Accounts
TLDR
The phylogeny of the species-rich clade of the Neotropical frog genus Leptodactylus sensu stricto is presented on the basis of a total evidence analysis of molecular and non-molecular evidence sampled from > 80% of the 75 currently recognized species.

Improvements to resampling measures of group support
Several aspects of current resampling methods to assess group support are reviewed. When the characters have different prior weights or some state transformation costs are different, the frequencies
The measurement of test severity , significance tests for resolution , and a unified philosophy of phylogenetic inference
TLDR
A new interpretation is described that equates p ( e|b ) with the probability of the data in the absence of a hypothesis of phylogenetic resolution, that is with the likelihood of an unresolved or polytomous tree.
Assessment of the accuracy of matrix representation with parsimony analysis supertree construction.
TLDR
It is suggested that MRP supertree construction provides a reasonable approximation of a total evidence solution and that weighted MRP should be used whenever possible.
Data exploration in phylogenetic inference: scientific, heuristic, or neither
  • Taran Grant, A. Kluge
  • Biology
    Cladistics : the international journal of the Willi Hennig Society
  • 2003
TLDR
It is concluded that undue emphasis has been placed on data exploration in phylogenetic inference, and phylogeneticists are urged to consider more carefully the relevance of the methods that they employ.
From conviction to anti‐superfluity: old and new justifications of parsimony in phylogenetic inference
TLDR
According to ASP, explanatory power is maximized by minimizing the number of transformation events required to explain the character‐states of the terminal taxa as hypotheses of homology, where the concept homology is restricted to just those inherited“things” shared by species.
Combining trees as a way of combining data sets for phylogenetic inference, and the desirability of combining gene trees
TLDR
A procedure of combining trees obtained from data sets of different kinds, similar to Brooks's technique but for a different purpose, with the aim of combining these data sets, is detailed along with examples used in five unrepeated combinations from a total of 15 published datasets.
SKEWNESS AND PERMUTATION
TLDR
The skewness criterion of phylogenetic structure in data is too sensitive to character state frequencies, is not sensitive enough to number of characters, and relies on counts of arbitrarily‐resolved bifurcating trees to give misleading results.
