TLDR
With the ratchet, Goloboff's NONA, and existing computer hardware, data sets that were previously intractable or required months or years of analysis with PAUP* can now be adequately analyzed in a few hours or days.

TNT, a free program for phylogenetic analysis

TL;DR: Through the use of a number of native commands and a simple but powerful scripting language, TNT allows the user an enormous flexibility in phylogenetic analyses or simulations.

phangorn: Phylogenetic analysis in R

TL;DR: Phangorn is a package for phylogenetic reconstruction and analysis in the R language that offers the possibility of reconstructing phylogenies with distance based methods, maximum parsimony or maximum likelihood (ML) and performing Hadamard conjugation.

Sequence-Based Species Delimitation for the DNA Taxonomy of Undescribed Insects

TL;DR: In this paper, the authors use mitochondrial DNA variation to delimit species in a poorly known beetle radiation in the genus Rivacindela from arid Australia, using a new likelihood method that determines the point of transition from species-level (speciation and extinction) to population-level evolutionary processes.
Journal ArticleDOI

TNT version 1.5, including a full implementation of phylogenetic morphometrics.

TL;DR: Using algorithms described in this paper, searches for landmark data can be made tens to hundreds of times faster than it was possible before, thus making phylogenetic analysis of landmarks feasible even on standard personal computers.

Phylogenetics of seed plants: an analysis of nucleotide sequences from the plastid gene rbcL.

TL;DR: Two exploratory parsimony analyses of DNA sequences from 475 and 499 species of seed plants, respectively, representing all major taxonomic groups indicate that rbcL sequence variation contains historical evidence appropriate for phylogenetic analysis at this taxonomic level of sampling.

TL;DR: In this article, the set of most parsimonious trees for a data matrix may include several distinct classes (islands) of trees, each one differing from the next by a single rearrangement of branches.

A Report on “One Day Symposium on Numerical Cladistics”

TL;DR: A recent symposium on numerical cladistics addressed novel methods for searching tree space, applications of randomizations in cladistic analysis, and data management, and modifications to parsimony jackknifing that improved its accuracy when compared to normal heuristic searches.
