Abstract— Logical equivalence between the notions of homology and synapomorphy is reviewed and supported. So‐called transformational homology embodies two distinct logical components, one related to comparisons among different organisms and the other restricted to comparisons within the same organism. The former is essentially hierarchical in nature, thus being in fact a less obvious form of taxic homology. The latter is logically equivalent to so‐called serial homology in a broad sense… Expand
The notion of homology in current comparative biology
Current notions on homology, and its recognition, causation, and explanation are reviewed in this report. The focus is primarily on concepts because the formulation of precise definitions of homologyExpand
The contemporary concepts of homology in biology: A theoretical review
  • I. Pavlinov
  • Biology, Medicine
  • Biology Bulletin Reviews
  • 2012
A review of the contemporary theoretical concepts of homology addresses the following issues: the ontological status of homology (nominalistic, realistic, and conceptualistic interpretations); theExpand
Homology: A Philosophical and Biological Perspective
Current discussions of the concept of homology center on metaphysical and epistemological issues: what are homologs, and how can they be discovered? Homology is the relation of common ancestry sharedExpand
Quantitative tests of primary homology
TLDR
Here a method is presented to compare quantitatively the ability of traditional homology criteria, and competing homology schema, to explain morphological observations, and whether primary homology should be insulated as “prior knowledge” from the usual issues and demands that quantitative phylogenetic analyses pose.

Assessing similarity: on homology, characters and the need for a semantic approach to non‐evolutionary comparative homology
The problem of homology has been a consistent source of controversy at the heart of systematic biology, as has the step of morphological character analysis in phylogenetics. Based on a clearExpand
The Formation of the Theory of Homology in Biological Sciences
TLDR
This study represents a historical overview of the development of the homology concept followed by some clues on how to navigate the pluralistic terminology of modern approaches to homology. 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
Similarity, parsimony and conjectures of homology: The chelonian shoulder girdle revisited
TLDR
It is argued that homology can be equated with synapomorphy (a shared evolutionary novelty uniting a monophyletic group), and a cladistic analysis is performed involving the trait in question and all other informative traits identified. Expand
Inference of molecular homology and sequence alignment by direct optimization.
TLDR
The use of the term "homology" as it is applied to molecular data is examined, and the concept of molecular homology one must accept if cladograms are to be interpreted as phylogenetic estimates is critique. Expand
Assessing similarity: a semantic approach to non-evolutionary comparative homology
TLDR
This approach to comparative homology provides an essential methodological framework for generalizing over individual organisms and identifying and demarcating anatomical structural kinds and represents an important contribution to the theoretical and methodological foundation of both morphology and comparative biology.

In this paper certain long-standing problems in the definition and interpretation of biological homology are discussed. A logical reconstruction of homology is proposed, and shown to generate aExpand
Homology -A Continuing Challenge
TLDR
A flexible approach taking into consideration the existing variety of structural relationships is suggested, which recognizes different kinds and grades of struc- tural relationships, i.e., 1:1 correspondences and partial correspondences. Expand
Homology and Phylogeny: Morphology and Systematics
TLDR
In the general discussion it is emphasized that the phylogenetic framework in which the definition of homology is placed specifies levels between and within which comparisons can most usefully be made, so enabling problems of interest to both systematists and morphologists to be tackled. Expand

TLDR
There are more kinds of homologous relation between molecular sequences than in morphology, and the terms paraxenology and plerology are proposed for two of these kinds--respectively, the consequence of multiple xenology and of gene conversion. Expand

TLDR
There could be no more appropriate celebration of the centenary of Owen's definitions than the wise adoption of these terms as he defined them, for such action would inevitably lead to a clearer and more effective analysis of the data of comparative zoology. Expand

This review focuses largely on the descriptive issues of animal ontogeny and systematics, and assumes that the genome and epigenetic phenomena produce a morphological superstructure within which are embedded the traits the authors observe and describe. Expand
