Today, cladistics is the most popular method for inferring phylogenetic trees from morphological data. In the 1990s, the development of effective polymerase chain reaction techniques allowed the application of cladistic methods to biochemical and molecular genetic traits of organisms, vastly expanding the amount of data available for phylogenetics.
Transformed cladistics, also known as pattern cladistics is an epistemological approach to the cladistic method of phylogenetic inference and classification that makes no a priori assumptions about common ancestry. It was advocated by Norman Platnick, Colin Patterson, Ronald Brady and others in the 1980s, but has few modern proponents.
Three-taxon analysis (or TTS, three-item analysis, 3ia) is a cladistic based method of phylogenetic reconstruction. Introduced by Nelson and Platnick in 1991 [2] to reconstruct organisms' phylogeny, this method can also be applied to biogeographic areas. It attempts to reconstruct complex phylogenetic trees by breaking the problem down into ...
The cladistic method has emerged since the 1960s. [55] In 1958, Julian Huxley used the term clade. [20] Later, in 1960, Cain and Harrison introduced the term cladistic. [20] The salient feature is arranging taxa in a hierarchical evolutionary tree, with the desired objective of all named taxa being monophyletic. [55]
Cladistic methods attempt to solve those problems. Consider for example songbirds. These can be divided into two groups – Corvida, which retains ancient characteristics of phenotype and genotype, and Passerida, which has more modern traits. But only the latter are a group of closest relatives; the former are numerous independent and ancient ...
The cladistic form of analysis of evolutionary relationships cannot falsify any genuine evolutionary scenario incorporating serial transformation, according to Zander. [ 14 ] Zander has detailed methods for generating support measures for molecular serial descent [ 15 ] and for morphological serial descent using Bayes factors and sequential ...

In the early 1990s this led him into a debate with Derek Briggs, who had begun to apply quantitative cladistic techniques to the Burgess Shale fossils, about the methods to be used in interpreting these fossils. [67] Around this time cladistics rapidly became the dominant method of classification in evolutionary biology.
