Species Trees Forcing Parsimony to Fail
نویسندگان
چکیده
The fact that Parsimony may fail is not new. However, here we proved that no mater of what topology the true 9-taxon and greater species tree is the only thing you need to fail Parsimony is to have in this tree three consecutive edges with lengths T1, T2, T3 of some proportions. Obviously, the probability to meet these lengths is growing in general with the size of species tree. Therefore, Parsimony can be applied only when one knows for sure that the described lengths cannot be met in the tree.

Phylogenies ; The evolutionary histories of groups of species are one of the most widely used tools throughout the life sciences, as well as objects of research with in systematic, evolutionary biology. In every phylogenetic analysis reconstruction produces trees. These trees represent the evolutionary histories of many groups of organisms, bacteria due to horizontal gene transfer and plants du...
متن کاملGenetic Relationships among Populations of Sceloporus Undulatus Fail to Support Present Subspecific Designations
The eastern fence lizard, Sceloporus undulatus, is a broadly distributed polytypic species. We surveyed allozyme variation with the goal of generating an intraspecific phylogeny to evaluate the current classification of the species. We electrophoretically assayed 24 loci from 12 populations of S. undulatus, which comprised 6 of the 11 recognized subspecies, 3 additional species of Sceloporus (S...
متن کاملecceTERA: comprehensive gene tree-species tree reconciliation using parsimony
UNLABELLED : A gene tree-species tree reconciliation explains the evolution of a gene tree within the species tree given a model of gene-family evolution. We describe ecceTERA, a program that implements a generic parsimony reconciliation algorithm, which accounts for gene duplication, loss and transfer (DTL) as well as speciation, involving sampled and unsampled lineages, within undated, fully ...

The proliferation of gene data from multiple loci of large multigene families has been greatly facilitated by considerable recent advances in sequence generation. The evolution of such gene families, which often undergo complex histories and different rates of change, combined with increases in sequence data, pose complex problems for traditional phylogenetic analyses, and in particular, those ...
