Homology in cladistics is reviewed. The definition of important terms is explicated in historical context. Homology is not synonymous with synapomorphy: it includes symplesiomorphy, and Hennig clearly included both plesiomorphy and synapomorphy as types of homology. Homoplasy is error, in coding, and is analogous to residual error in simple regression. If parallelism and convergence are to be distinguished, homoplasy would be evidence of the former and analogy evidence of the latter. We discuss… Expand
Homology and errors
TLDR
An alternative definition of homology is proposed and primary and secondary homology are defended as realistic representations of discovery procedures in comparative biology, recognizable even in Direct Optimization. Expand
Homology and synapomorphy‐symplesiomorphy—neither synonymous nor equivalent but different perspectives on the same phenomenon
TLDR
I, however, do not consider the concept of homology equal or synonymous to that of synapomorphy and symplesiomorphy, as they represent different perspectives on the same phenomenon, i.e. correspondence by common origin. Expand
Homology and misdirection
Hennig (1966) recognized symplesiomorphies as homologies, and that view is logically correct under the concept of homology (homogeny) prevalent among evolutionists since 1870. Nelson and PlatnickExpand

TLDR
Four examples – three from plants and one from animals – demonstrate that homologous developmental mechanisms can regulate a range of morphological relations including analogy, homoplasy and examples of uncertain homology. Expand
Confusing homologs as homologies: a reply to “On homology”
TLDR
It seems that systematists, taxonomists, historians and philosophers of biology, perhaps all biologists and palaeontologists, never tire of discussing, expanding and redefining the homology concept. Expand
Homology and Homoplasy: A Philosophical Perspective
TLDR
A new theory about the mechanical causes of homology is proposed, which states that homologies of character are due to the development of a certain kind of genetic regulatory network called a character identity network. Expand

TLDR
Anatomical characters are found to be more reliable than embryological homology criteria when comparing adult structures, because anatomical characters more closely reflect the actions of the developmental genetic mechanisms of character individuation. Expand
Homology in Classical and Molecular Biology 1
Hypotheses of homology are the basis of comparative morphology and comparative molecular biology. The kinds of homologous and nonhomologous relations in classical and molecular biology are exploredExpand
Are homology and synapomorphy the same or different?
TLDR
In this letter, some points explored by Brower and de Pinna (2012) are reviewed, and it is shown why their alternative definition of homology cannot totally accommodate homology and synapomorphy as synonymous. Expand
Evo-devo mechanisms underlying the continuum between homology and homoplasy.
TLDR
This work looks into the nature of morphological units and their degrees of modification, which will provide the starting point for restructuring the concept of "homology," keeping the use of homology as the identity of an anatomical part, and homogeny, as the specific variation of that anatomical part during evolution.

CONCEPTS AND TESTS OF HOMOLOGY IN THE CLADISTIC PARADIGM
TLDR
Logical equivalence between the notions of homology and synapomorphy is reviewed and supported, and a general theoretical solution is proposed to determine evolution of characters with ambiguous distributions, based on the notion of maximization ofHomology propositions. Expand
THREE STEPS OF HOMOLOGY ASSESSMENT
Abstract — In 1991 de Pinna (Cladistics 7: 367–394) coined the term primary homology as the putative homology statements prior to tree reconstruction. However, some confusion still exists regardingExpand
Homology as a parsimony problem: a dynamic homology approach for morphological data
TLDR
I explore the testing of alternative hypotheses of morphological correspondences in a quantitative cladistic context, and proposes a Bremer support for anatomical interpretations when the specific interpretation is not used. Expand
Coding behavioural data for cladistic analysis: using dynamic homology without parsimony
TLDR
A new method for the direct optimization of behavioural data, a method that relies on the richness of this database to delimit the characters, and on dynamic procedures to establish character state identity, an important step towards the practical integration of the evolutionary and ecological perspectives on diversity.

TLDR
The present paper proposes the first application of direct optimization to morphological characters, in the case study of the phylogeny of Odontellidae, and a new homology regime is compared to the traditional homology scheme. Expand

The criterion of inter‐data set congruence, both character based and topological, are applied to two data sets to elucidate and potentially discriminate among these parsimony‐based ideas. Expand
Toward Defining the Course of Evolution: Minimum Change for a Specific Tree Topology

A method is presented that is asserted to provide all hypothetical ancestral character states that are consistent with describing the descent of the present-day character states in a minimum number of changes of state using a predetermined phylogenetic relationship among the taxa represented.
