Abstract— Branch support is quantified as the extra length needed to lose a branch in the consensus of near‐most‐parsimonious trees. This approach is based solely on the original data, as opposed to the data perturbation used in the bootstrap procedure. If trees have been generated by Farris's successive approximations approach to character weighting, branch support should be examined in terms of weighted extra length needed to lose a branch. The sum of all branch support values over the tree… Expand
Measuring Support for Phylogenies: The “Proportional Support Index”
The total support index (Bremer, 1994), a measure of cladogram support, is influenced both by character incongruence and by uninformative characters. A modified version of this index is thereforeExpand

Branch Lengths Do Not Indicate Support—Even in Maximum Likelihood
It is still common to see the branch lengths of “phylograms”1 interpreted as indicating support for groups. This is unfortunate, for it is easy to find cases in which long branches do not indicateExpand

TLDR
Direct measures of support may play a more specific role in phylogenetic inference by providing the tools to search for falsifiers that could be the subject of future rounds of hypothesis testing. Expand
Bias in tree searches and its consequences for measuring group supports.
TLDR
Two methods commonly used for finding phylogenetic trees consist of randomizing the input order of species in multiple addition sequences followed by branch swapping, or using random trees as the starting point for branch swapping. Expand
Partitioned Bremer support and multiple trees
Partitioned Bremer support (PBS) is a valuable means of assessing congruence in combined data sets, but some aspects require clarification. When more than one equally parsimonious tree is foundExpand
Asymmetry and Explanations
TLDR
If poorly supported groups are removed, as with parsimony jackknifing, well-structured real data can still give strong asymmetry, while random matrices simply yield unresolved trees, obviating Colless’ argument. Expand

TLDR
This new measure of robustness allows calculation of summary probabilities of subclade and tree reconstruction and is conditional on a particular data set and optimization method but may also compare support from conflicting gene trees. Expand
Asymmetry and Explanations
In Colless’ (1995,Syst. Biol. 44, 102–108) results, cladograms for randomly generated matrices were strongly asymmetrical, and he used this to maintain that real cladograms provide little evidence onExpand
A chain is no stronger than its weakest link: double decay analysis of phylogenetic hypotheses.
TLDR
Double decay analysis is introduced, a new approach to assessing support for phylogenetic relationships that provides a more comprehensive summary and facilitates a better understanding of the strengths and weaknesses of complex phylogenetic hypotheses than does traditional decay analysis. Expand

COULD A CLADOGRAM THIS SHORT HAVE ARISEN BY CHANCE ALONE?: ON PERMUTATION TESTS FOR CLADISTIC STRUCTURE
TLDR
A means of quantitative evaluation is presented based on tree length of the most parsimonious tree reflects the degree to which the observed characters co‐vary such that a single tree topology can explain shared character states among the taxa. Expand
CONFIDENCE LIMITS ON PHYLOGENIES: THE BOOTSTRAP REVISITED
TLDR
Additional applications of the bootstrap are proposed which provide useful information about phylogeny even when many clades are found not to be supported with confidence, and the distinction between hypotheses about membership in particular clades and hypotheses about entire topologies is discussed.

CHARACTER REMOVAL AS A MEANS FOR ASSESSING STABILITY OF CLADES
TLDR
Minimum character removal scores are discoverable by a procedure known as successive character removal, in which separate cladistic analyses are conducted of all possible data sets derived by the removal of individual characters and character combinations of successively increasing number. Expand

TLDR
The recently‐developed statistical method known as the “bootstrap” can be used to place confidence intervals on phylogenies and shows significant evidence for a group if it is defined by three or more characters. Expand

TLDR
Application of the bootstrap test revealed significant support for the hypothesis that the thylacine is not an outgroup to the Australian marsupials, and is the sister of the Dasyuridae. Expand

TLDR
The findings suggest that cladistics is being redefined in ways that contradict the practices and principles responsible for its pre-eminence in phylogenetic inference, including the bootstrap and jackknife resampling techniques. Expand
