Phylogenetic tree-building

International Journal for Parasitology, 1996
Cladistic analysis is an approach to phylogeny reconstruction that groups taxa in such a way that those with historically more-recent ancestors form groups nested within groups of taxa with more-distant ancestors. This nested set of taxa can be represented as a branching diagram or tree (a cladogram), which is an hypothesis of the evolutionary history ...

Phylogenetic Networks with Every Embedded Phylogenetic Tree a Base Tree

Bulletin of Mathematical Biology, 2015
We show that the class of tree-child networks is precisely the class of tree-based networks with the property that every embedded phylogenetic tree is a base tree.

Phylogenetic Trees

2000
Abstract Phylogenetic analysis of DNA or protein sequences has become an important tool for studying the evolutionary history of organisms from bacteria to humans. Since the rate of sequence evolution varies extensively with gene or DNA segment (Wilson et al. 1977; Dayhoff et al.

Statistics for phylogenetic trees

Theoretical Population Biology, 2003
This paper poses the problem of estimating and validating phylogenetic trees in statistical terms. The problem is hard enough to warrant several tacks: we reason by analogy to rounding real numbers, and dealing with ranking data. These are both cases where, as in phylogeny the parameters of interest are not real numbers.

X-trees and phylogenetic trees

2003
Abstract Phylogenetic trees’ provide a standard graphical representation of evolutionary relation-ships in biology. However, from a mathematical perspective, it is natural to consider a slightly more general class of objects called ‘X-trees‘. Briefly, an X-tree is a finite tree in which some vertices (including all vertices of degree one

Molecular Phylogenetic Tree

2004
It is now relatively easy to determine the nucleotide sequence of DNA and construct a phylogenetic tree with the aid of a personal computer using techniques taken from analytical biochemistry. To be able to effectively evaluate the resultant phylogenetic tree, however, one must have a fundamental understanding of the DNA structure, population genetics,

Tree-based phylogenetics

2023
AbstractThis major subchapter introduces tree-based phylogenetic methods and their history before applying the method to early Germanic, detailing every step in the modelling process. The main intermediate results of this chapter are that only few ‘hard’ splits between Germanic subclades can be established, most prominently between West and North ...
