PhylogenySimilarityDefinition Homology, one of the key concepts in modern evolutionary biology, refers to the similarity between characteristics of organisms due to a common origin from a common ancestor (i.e., shared ancestry). Homology can be applied to organs and anatomical structures but also ...

In this article the interface between development and homology is discussed. Development is here interpreted as a sequence of evolutionarily independent stages. Any approach stressing the importance of specific developmental stages is rejected. A homology definition is favoured which includes similarity and ...
An alternative definition of homology is proposed. The Willi Hennig Society 2012.doi:10.1111/j.1096-0031.2012.00398.xAndrew V.Z. BrowerEvolution and Ecology Group, Department of Biology, Middle Tennessee State University, Murfreesboro, TN 37132, USA;Mario C.C. de Pinna...
If the trait is congruent with the resultant phylogeny, it is accepted as homologous in all taxa which possess it. If the trait is incongruent with the phylogeny, it is interpreted as homoplasious in certain taxa. This has been termed the test of congruence (Patterson, 1982; de Pinna, ...
Spermatophore capsular patterns appears to be congruent with a recent phylogeny of the order Scorpiones based on phylogenomic data that placed Bothriuridae outside of Scorpionoidea andLiochelesoutside of Hormuridae, in contradicton with earlier phylogenetic reconstructions based on morphology. This rai...
