Because coalescent theory is stochastic, it allows for statistical testing and estimates of variance, unlike phylogenetics. Coalescent theory can be applied to construct genealogies, but it is inappropriate (well, basically impossible) to apply phylogenetics for parameter estimation. I wrote this based off of this paper: Rosenberg and Nordborg ...

11/9/2018 · Coalescent theory. A recurring analytical method, both within The G-CAT and the broader ecological genetic literature, is based on coalescent theory.

Coalescent theory Coalescent theory is a model of how gene variants sampled from a population may have originated from a common ancestor. In the simplest case, coalescent theory assumes no recombination, no natural selection, and no gene flow or population structure, meaning that each variant is equally likely to have been passed from one generation to the next.

In biology, phylogenetics (Greek: phyle = tribe, race and genetikos = relative to birth, from genesis = birth) is the study of evolutionary relatedness among various groups of organisms (e.g., species, populations). Also known as phylogenetic systematics or cladistics, phylogenetics treats each species as a group of lineage-connected individuals.

Abstract Under the coalescent model for population divergence, lineage sorting can cause considerable variability in gene trees generated from any given species tree. In this paper, we derive a method for computing the distribution of gene tree topologies given a bifurcating species tree for trees with an arbitrary number of taxa in the case that there is one gene sampled per species.
