Phylogenetic test of the molecular clock and linearized trees.
To estimate approximate divergence times of species or species groups with molecular data, we have developed a method of constructing a linearized tree under the assumption of a molecular clock. We present two tests of the molecular clock for a given topology: two-cluster test and branch-length test. The two-cluster test examines the hypothesis of the molecular clock for the two lineages create...
متن کاملEstimation of evolutionary distance for reconstructing molecular phylogenetic trees.
The most commonly used measure of evolutionary distance in molecular phylogenetics is the number of nucleotide substitutions per site. However, this number is not necessarily most efficient for reconstructing a phylogenetic tree. In order to evaluate the accuracy of evolutionary distance, D(t), for obtaining the correct tree topology, an accuracy index, A(t), was proposed. This index is defined...
متن کاملPhylogenetic trees
We introduce the package PhylogeneticTrees for Macaulay2 which allows users to compute phylogenetic invariants for group-based tree models. We provide some background information on phylogenetic algebraic geometry and show how the package PhylogeneticTrees can be used to calculate a generating set for a phylogenetic ideal as well as a lower bound for its dimension. Finally, we show how methods ...
متن کاملVisualization of Phylogenetic Trees
We present a spring-embedder model for drawing rooted and unrooted phylogenetic trees with straight edges. Our heuristic strives for uniform edge lengths, and we develop it in analogy to forces in natural systems, for a simple, elegant, conceptually intuitive, and efficient algorithm. These algorithms are implemented on a web-based phylogeny visualization system that interoperates with existing...
متن کاملMolecular evolutionary phylogenetic trees based on minimum description length principle
Ever since the discovery of a molecular clock, many methods have been developed to reconstruct the molecular evolutionary phylogenetic trees. In this paper, we deal with this problem from the viewpoint of an inductive inference and apply Rissanen’s minimum description length principle to extract the minimum complexsty phylogenetic tree. OUT method describes the complexity of molecular phylogene...
