The relationship between speciation times and the corresponding times of gene divergence is of interest in phylogenetic inference as a means of understanding the past evolutionary dynamics of populations and of estimating the timing of speciation events. It has long been recognized that gene...

A formalism for the analysis of DNA-sequences is presented. It develops the concept of a composition vector potential which incorporates intrinsic double-strand and four-base symmetries. The vector potential allows for straightforward coarse graining and graphical representation of whole...

We propose a heuristic approach to the detection of evidence for recombination and gene conversion in multiple DNA sequence alignments. The proposed method consists of two stages. In the first stage, a sliding window is moved along the DNA sequence alignment, and phylogenetic trees are sampled...
