Inferring the root of a phylogenetic tree.
Phylogenetic trees can be rooted by a number of criteria. Here, we introduce a Bayesian method for inferring the root of a phylogenetic tree by using one of several criteria: the outgroup, molecular clock, and nonreversible model of DNA substitution. We perform simulation analyses to examine the relative ability of these three criteria to correctly identify the root of the tree. The outgroup an...
متن کاملThe root of the phylogenetic tree of human populations.
Although African populations have been shown to be most divergent from any other human populations, it has been difficult to establish the root of the phylogenetic tree of human populations since the rate of evolutionary change may vary from population to population owing to the fluctuation of population size and other factors. However, the root can be determined by using the chimpanzee as an o...

s of posters • Krzysztof Bartoszek (Chalmers U., Gothenburg) Conditioned branching processes and phenotype evolution Abstract. Conditioned branching processes have recently received a lot of attention in the biomathematical literature. They are useful for modelling and developing software in the field of phylogenetic tree inference. However on top of this they can also be combined with continuo...
متن کاملInferring a Tree from Walks
A walk in an undirected edge-colored graph G is a path containing all edges of G. The tree inference from a walk is, given a string x of colors, finding the smallest tree that realizes a walk whose sequence of edge-colors coincides with x. We prove that the problem is solvable in O(n) time, where n is the length of a given string, We furthermore consider the problem of inferring a tree from a f...
