“Homology” has the precise meaning in biology of “having a common evolutionary origin,” but it also carries the loose meaning of “possessing similarity or being matched.” Its rampant use in the loose sense is clogging the literature on protein and nucleic acid sequence comparisons with muddy writing and, in some cases, muddy thinking In its precise biological meaning, “homology” is a concept of quality. The word asserts a type of relationship between two or more things. Thus, amino acid or… Expand

Topics from this paper

Genes and homology
Homology is a property that describes evolutionary history, just as with bird wings and bat wings, perceived similarities between sequences need not be due to a common evolutionary origin. Expand
The misuse of terms in scientific literature
Authors should be asked to present articles which agree not only with general rules (molecule nomenclature, English language, reference formats) but also for the correctness in the usage of the term “homology”, and any other term for which public debates have evidenced a bad habit in their misuse. Expand
Molecular homology and multiple-sequence alignment: an analysis of concepts and practice
This work presents examples of molecular-data levels at which homology might be considered, and proposes terminology with which to better describe and discuss molecular homology at these levels, and sheds light on the multitude of automated procedures that have been created for multiple-sequence alignment. Expand
Homology in Molecular Phylogenetics: A Parsimony Perspective
One of the goals is to discuss the ways in which parsimony analysis is distinguished from other approaches to phylogeny reconstruction, such as distance or maximum likelihood estimation (ML), and to relate these differences to general concerns about character homology. Expand
Towards a complete sequence homology concept : Limitations and Applications
This work shows that misguided E-value computation coupled with non-globular regions embedded in domain model library not only causes annotation errors in public databases but also limits the extrapolation power of protein function prediction tasks. Expand
Optimal Sequence Alignment and Its Relationship with Phylogeny
The main motivation for predicting functions of hundreds of thousands of genes and proteins found across genomes and proteomes is variations within a family of related nucleic acid or proteinExpand
Molecular homology and DNA hybridization
DNA hybridization is analyzed with respect to the problems of recognizing homology and using it in phylogenetic inference, where symplesiomorphic homology will not confound DNA hybridization phylogenies, but nonhomologous identities that act like apomorphic homologies can lead to inaccurate reconstructions. Expand
Homology and the origin of correspondence
It is speculated that further understanding of morphogenesis might enable biologists to give a theoretically deeper definition of homology alongsimilar lines: an account which makes reference to the concrete mechanisms that operate in organisms. Expand
When it comes to homology, bad habits die hard.
The scientific community has discussed for a long time the use and misuse of the term ‘homology’, but nowadays it is often wrongly used instead of ‘similarity’ in articles describing a comparison of protein or nucleic acid sequences. Expand
Homology in coding and non-coding DNA sequences: a parsimony perspective
The use of non-coding DNA can result in more laborious coding, but at the same time in more corroborated hypotheses, mirroring their accuracy for phylogenetic inference. Expand
