A Framework for Representing Reticulate Evolution

Acyclic directed graphs (ADGs) are increasingly being viewed as more appropriate for representing certain evolutionary relationships, particularly in biology, than rooted trees. In this paper, we develop a framework for the analysis of these graphs which we call hybrid phylogenies. We are particularly interested in the problem whereby one is given a set of phylogenetic trees and wishes to deter...

A program for calculating and displaying compatibility matrices as an aid in determining reticulate evolution in molecular sequences

Reticulate evolution in molecular sequences is caused by recombination or gene conversion, and may interfere with the reconstruction of evolutionary history. This paper presents a program which calculates compatibility matrices for detecting reticulate evolution. In addition to visual inspection of matrices, they can be analysed statistically for clustering. The method is demonstrated using hum...

Smile Analyzer: A Software Package for Analyzing the Characteristics of the Speech and Smile

Taking into account the factors related to lip-tooth relationships in orthodontic diagnosis and treatment planning is of prime importance. Manual quantitative analysis of facial parameters on photographs during smile and speech is a difficult and time-consuming job. Since there is no comprehensive and user-friendly software package, we developed a software program called "Smile Analyzer" in the...

Phylogenetic analysis under reticulate evolution.

The usual assumption that species have evolved from a common ancestor by a simple branching process--where each branch is genetically isolated--has been challenged by the observation of frequent hybridization between species in natural populations. In fact, most plant species are thought to have hybrid origins. This reticulate pattern of species evolution has posed problems in the definition of...
