Phylogenetic trees can improve the power of comparative sequence analyses by placing raw sequence differences into their historical context — offering an understanding of how the sequences that we see today were created.

Neighbour joining provides an extremely fast estimate of the phylogeny that is accurate if relatively little evolution has occurred between sequences. Parsimony can be effectively used if the sampling of sequences is dense so, long branches are avoided , but this can be difficult to guarantee.

Maximum-likelihood techniques use models of sequence evolution to allow for unseen events and account for forces such as variation in rate at different sites in a sequence. These models can improve tree inference when the sequences are not closely related. Bootstrapping provides a robust though potentially time-consuming way to assess confidence in phylogenetic estimates.

Bayesian techniques rely on the specification of a prior probability and the likelihood from the data and models of evolution to assign a posterior probability to hypotheses. Bayesian techniques can account for uncertainty in parameter estimates by marginalizing over 'integrating out' parameters. Marginalization makes the use of complex models of sequence evolution more robust.

Markov chain Monte Carlo is an algorithm that allows for efficient estimation of the posterior probability, making Bayesian phylogenetics feasible for most data sets. The construction of evolutionary trees is now a standard part of exploratory sequence analysis. Bayesian methods for estimating trees have recently been proposed as a faster method of incorporating the power of complex statistical models into the process. Researchers who rely on comparative analyses need to understand the theoretical and practical motivations that underlie these new techniques, and how they differ from previous methods.

The ability of the new approaches to address previously intractable questions is making phylogenetic analysis an essential tool in an increasing number of areas of genetic research. Yang, Z.
