217 Cladistics — parsimony analysis — is a search for hierarchy. Any philosophical rationale for cladistics must therefore justify the assumption that organisms are most appropriately shoehorned into a (mostly dichotomous) non-overlapping hierarchy, rather than some other pattern. Divergent evolution — anagenesis and cladogenesis — is usually invoked. However, many previous workers often described as ‘pattern cladists’ (e.g. Platnick 1979; Nelson & Platnick 1981; Brady 1985, 1994; Brower 2000… 
Cladistics, phylogeny, evidence and explanation — a reply to Lee
TLDR
In this short Point of View, this author will address Lee (2002)’s particular criticisms of Brower (2000), and explore some more general ramifications of his metaphysical stance.
Towards a phylogenetic classification of Lychnophorinae (Asteraceae: Vernonieae)
TLDR
The results show that syncephaly probably appeared independently three of four times in the course of evolution of American Vernonieae, and a new classification of the subtribe Lychnophorinae is proposed, involving three main lineages not closely related.
Norms, Culture and Identity
Stereotypical thinking is threatening progress, not the least within our field of sport and exercise psychology. If you belong to the ‘in-group’ you may not even think that you are privileged, but if
Analysis of arterial intimal hyperplasia: review and hypothesis

TLDR
This work argues that the question itself is misplaced because it implies that intimal hyperplasia is a novel pathological phenomenon caused by new mechanisms, while a simple inquiry into arterial morphology shows the opposite is true.

The paradigm of stimulus-driven emotional learning is embraced within a more integral field of machine learning. A computational model is suggested, where the actions of stimuli are represented by

PHYLOGENETIC SYSTEMATICS OR NELSON'S VERSION OF CLADISTICS?
TLDR
It is argued that the relation between phylogenetic systematics and the principle of common descent not only separates this approach from Nelson's version of cladistics by a fundamental conceptual gap but also enables it to resolve what Nelson sees as incompatibihties between cladistics and theories about evolutionary processes.
Philosophy and the Transformation of Cladistics
TLDR
The main principles of the Hennigian system are that the basic process of organic evolution is the splitting of an ancestral species into two descendant species and that each dichotomy should be taken as marking the origin of two new units of classification; and that the hierarchic level of such units should be determined by the geological time when the dichotomy occurred.
On Groups, Existence and the Ordering of Nature
The notion of existence, or the meaning of the term "exist," is a central question of philosophy (Williams, 1981). It is therefore not surprising that it forms a point of argument for proponents of
Evolution Is Not a Necessary Assumption of Cladistics
TLDR
It is suggested that the philosophical support for the cladistic approach is strengthened by purging reference to descent with modification altogether and three general axioms necessary to justify cladistics—the discoverability of characters, hierarchy, and parsimony are reviewed.
Towards an inclusive philosophy for phylogenetic inference.
TLDR
It is concluded that progress in an inclusive phylogenetics will be well served by the rejection of cladistic philosophy, and the capacity to assess Popperian corroboration provides a framework in phylogenetics for learning from errors--cases where apparent good evidence is probable even without the hypothesis.
Circularity, evolution, systematics … and circularity
TLDR
Advocating inclusion or exclusion of all (or as many as possible) evolutionary principles from phylogenetic analysis is misguided, since phylogeny‐neutral principles are independently supported and can be included, while phylogeny-dependent principles are unjustified assumptions and should be excluded to avoid circularity.

Abstract— Before the publication of On the Origin of Species the standing patterns of natural history—common plan, homology, ontogenetic parallelism, and the hierarchy of groups — were taken as
Philosophy and Phylogenetic Inference: A Comparison of Likelihood and Parsimony Methods in the Context of Karl Popper's Writings on Corroboration
TLDR
It is argued that the concept of likelihood in general, and its application to problems of phylogenetic inference in particular, are highly compatible with Karl Popper’s philosophy, and that statistical methods proceed by the elimination of inadequate hypotheses.
