We contend that the move away from providing character evidence with phylogenies has diminished fish systematics and systematics in general, and amounts to a crisis. Present practices focus on solutions to matrices rather than on character homology, and rely on algorithms and statistics rather than biology to determine relationships. Optimization procedures in tree-building programs are phenetic and no longer employ homology, the original foundation of cladistics. Evidence for phylogenies is…

Exploring character conflict in molecular data
TLDR
Existing methods for exploring character conflict in molecular data such as spectral analysis, phylogenetic networks, likelihood mapping and sliding window analyses are briefly reviewed, but there is also a need for development of new tools to facilitate the analysis of large data sets.
Plesiomorphic character states cause systematic errors in molecular phylogenetic analyses: a simulation study

  • Medicine, Biology
    Cladistics : the international journal of the Willi Hennig Society
  • 2016
TLDR
It is concluded that many of the phylogenies published during the past decades may be false due to the neglected effects of symplesiomorphies.
The State of Phylogenetic Analysis: Narrow Visions and Simple Answers-Examples from the Diptera (flies).
TLDR
Current phylogenetic analyses have come to increasingly depend on DNA sequence-based characters, in spite of their tumultuous history of inconsistent results, so they should be viewed with caution and certainly not as a panacea as they are commonly portrayed.
Patterns of character evolution in phylogenies
TLDR
The main purpose in this letter is eliminating redundancy and increasing precision in the description of the patterns of character evolution in phylogenies, i.e., apomorphy and plesiomorphy.
Structuralism in Phylogenetic Systematics
Systematics based solely on structuralist principles is non-science because it is derived from first principles that are inconsistent in dealing with both synchronic and diachronic aspects of
The meaning of “phenetic”

  • Medicine, Biology
    Cladistics : the international journal of the Willi Hennig Society
  • 2012
Sir, A recent broadside critique of quantitative cladistic methods in ichthyology by Mooi and Gill (2010) applied the labels phylophenetics and phenetic cladistics to cladistic analytical approaches
New morphological evidence supports congruent phylogenies and Gondwana vicariance for palaeognathous birds
TLDR
A morphological phylogeny based mainly on new characters from the tongue apparatus and cranial osteology, with a theoretical ancestor as outgroup is reported, fully consistent with a Gondwana vicariance model of evolution.
The jazz of cladistics*
TLDR
In this metaphorical ‘composition’, nine ‘dissonant chords’ related to the drowning out of cladistic performance are commented on, including the false assumption of the irrelevance of classification and clashes amongst cladists themselves.
Use of Morphology in Criticizing Molecular Trees
TLDR
A phylogenomic analysis of arthropod relationships produced several surprising clades within Tetraconata (Pancrustacea) and it is shown that none of the criticisms can withstand scrutiny.
Numerical cladistics, an unintentional refuge for phenetics—a reply to Wiley et al .
TLDR
It is clarified that Hennig’s auxiliary principle pertains to potential synapomorphy, meaning for molecular work that it is the presence of a particular derived nucleotide that should be considered homologous until proven otherwise, not simply the alignments themselves.

Phylogeny of Gobioidei and Placement within Acanthomorpha, with a New Classification and Investigation of Diversification and Character Evolution
TLDR
This study integrates and expands previous molecular phylogenetic hypotheses to infer a comprehensive gobioid phylogeny, including a variety of outgroup taxa included to confirm sister taxon identity and position of the group among other acanthomorphs.
Efficiently resolving the basal clades of a phylogenetic tree using Bayesian and parsimony approaches: a case study using mitogenomic data from 100 higher teleost fishes.
TLDR
For this empirical study, the most efficient of the six approaches considered to resolve the basal clades when adding nucleotides to a dataset that consists of a single gene sampled for a small, but representative, number of taxa, is to increase character sampling and analyze the characters using the Bayesian method.
A Transitioning State or Harmful Mutation in Systematic Ichthyology? A Reply to Chakrabarty
TLDR
It is argued that taxonomies based on topologies without synapomorphies are ephemeral and add no long-term understanding of biology, and without a return to homology, the basic underpinnings of cladistics, phylogenetics will become irrelevant to other biological disciplines.
“COI-like” Sequences are Becoming Problematic in Molecular Systematic and DNA Barcoding Studies
TLDR
An illustrated discussion about quality control, pseudogenes, and sequence composition in COI-like accessions across Crustacea from published and unpublished studies is illustrated.
Phylophenetics: frequencies and polymorphic characters in genealogical estimation.
TLDR
Recovering evolutionary trees under a more realistic model of sequence evolution under the bootstrap and Gene trees in species trees are studied.
Pleuronectiform relationships : a cladistic reassessment
TLDR
It is concluded that phylogenetic knowledge within flatfishes remains very incomplete and the monophyletic status of speciose taxa such as the Pleuronectinae and Paralichthyidae will have to be reassessed before any fruitful statement of relationships can be formulated.
Repeatability of clades as a criterion of reliability: a case study for molecular phylogeny of Acanthomorpha (Teleostei) with larger number of taxa.
TLDR
This study represents the most extensive taxonomic sampling effort to date to collect new molecular characters for phylogenetic analysis of acanthomorph fishes, with new and reliable clades emerging from this study of the acanthomorphic radiation.
Homoplasy Increases Phylogenetic Structure
TLDR
Analysis of the largest nucleotide matrix treated to date—2538 rbc L sequences covering all major lineages of green plants— shows that although rapidly evolving and highly homoplastic, third positions contain most of the phylogenetic structure in the data.
Mitochondrial genome and a nuclear gene indicate a novel phylogenetic position of deep-sea tube-eye fish (Stylephoridae)
TLDR
The present results warrant a recognition of the new order for S. chordatus in fish systematics, and suggest that Stylephorus is not a lampridiform but is closely related to the order Gadiformes (cod and their relatives).
Molecular phylogeny of the gobioid fishes (Teleostei: Perciformes: Gobioidei).

  • 2003
TLDR
The phylogenetic hypothesis indicates that the morphological reduction observed in many goby species has been derived several times independently, and a single most parsimonious topology was obtained, with decay indices indicating strong support for most nodes.
