Is farris optimization perfect?: three-taxon statements and multiple branching

TL;DR: The three‐taxon approach to phylogenetic analysis separates the universe of cladograms into a larger number of classes of solutions showing decreasing degrees of fit to data than does conventional Farris optimization.
Journal ArticleDOI

Experimental systematics: sensitivity of cladistic methods to polarization and character ordering schemes

TL;DR: The results of simulations of the evolution of phenotypic traits under a Brownian motion model are presented to characterize differences in sensitivity between parsimony and 3ta to outgroup branch length, which affects the reliability of ancestral character state estimates, (2) character state ordering scheme, and (3) ingroup branch lengths that reflect the geological age of studied taxa.

A laid-back trip through the Hennigian Forests.

TL;DR: This paper operates directly with maximal relationships written just as trees, not as binary matrices, while also using the Average Consensus method instead of the MP analysis.
Journal ArticleDOI

On the Typology of Relations

TL;DR: A supertree approach that, if combined with the methodology of three-taxon statement analysis (3TA), may be seen as a powerful heuristic alternative to the application of conventional matrix/optimization-based methods used for the analysis of systematic data, and which currently forms the mainstream of contemporary phylogenetics.

Gene trees and species trees: Molecular systematics as one-character taxonomy

Jeff J. Doyle
- 01 Jan 1992 - 
TL;DR: A character phylogeny, in this case a gene tree, can be tested best by a parsimony analysis in which other characters are included, and each is an equivalent phylogenetic hypothesis, as is each non-molecular character, leading to the suggestion that direct combination is appropriate.
Journal ArticleDOI

Combining trees as a way of combining data sets for phylogenetic inference, and the desirability of combining gene trees

Bernard R. Baum
- 01 Feb 1992 - 
TL;DR: A procedure of combining trees obtained from data sets of different kinds, similar to Brooks's technique but for a different purpose, with the aim of combining these data sets, is detailed along with examples used in five unrepeated combinations from a total of 15 published datasets.
Journal ArticleDOI

Testing species phylogenies and phylogenetic methods with congruence

TL;DR: A combination of testing with the well-supported trees of natural groups, with simulations, and with those laboratory and domesticated taxa with known phylogenies is most likely to prove effective in establishing the strengths, weaknesses, and assump­ tions of different phylogenetic methods.

Cladistics: What's in a Word?

TL;DR: It is suggested that cladistics is being redefined in ways that contradict the practices and principles responsible for its pre‐eminence in phylogenetic inference.

On missing entries in cladistic analysis

TL;DR: The exact algorithms of two commonly used parsimony programs, Hennig86 and PAUP, sometimes produce different solutions, and sometimes produce resolutions that are not supported by the data being analysed, causing discrepancies in the treatment of missing entries.
