Interspecific comparisons have played a prominent role in evolutionary biology at least since the time of Charles Darwin. Since 1985, the “comparative method” has been revitalized by new analytical techniques that use phylogenetic information and by increased availability of phytogenies (often from molecular data sets). Because species descend from common ancestors in a hierarchical fashion, related species tend to resemble each other (elephants look like elephants); therefore, cross-species…

Phylogenetic analyses: comparing species to infer adaptations and physiological mechanisms.

An overview of phylogenetic approaches and their importance for studying the evolution of physiological processes and mechanisms is provided, and the conceptual framework underlying these methods are discussed, and when and how phylogenetic information should be employed are explained.

Interspecific comparison has a long and productive history in physiology, and several new statistical methods correct for problems caused by phylogenetic relatedness and descent with modification, the most common being phylogenetically independent contrasts.

Uncertainty in the reconstruction of ancestral character states and limitations on the use of phylogenetic comparative methods

The time has come for a critical reappraisal of phylogenetic methods for the analysis of comparative data, and a variety of methods have now been published.

A Generalized Permutation Model for the Analysis of Cross-Species Data

It is shown that the conventional, equally likely (EL) randomization model is a special case of the phylogenetic permutations (PP), and an application of the method is presented to test the correlation between two traits with cross-species data.

Phylogenetic approaches in comparative physiology

It is the personal opinion that the incorporation of phylogeny information into comparative studies has been highly beneficial, not only because it can improve the reliability of statistical inferences, but also because it continually emphasizes the potential importance of past evolutionary history in determining current form and function.

Using the Past to Predict the Present: Confidence Intervals for Regression Equations in Phylogenetic Comparative Methods

Passengerines exhibit a lower rate of evolution in both body mass and mass‐corrected BMR; passerines also have significantly smaller body masses than their sister clade, which may justify separate, clade‐specific allometric equations for prediction of avian basal metabolic rates.

Phylogenetic Analysis and Comparative Data: A Test and Review of Evidence

Simulations show λ to be a statistically powerful index for measuring whether data exhibit phylogenetic dependence or not and whether it has low rates of Type I error, which demonstrates that even partial information on phylogeny will improve the accuracy of phylogenetic analyses.

Chapter 11 Phylogenetic tests for differences in shape and the importance of divergence times

Thirteen samples of viverravid carnivorans from the paleogene of the Bighorn Basin, Wyoming were compared, indicating that long-term rates of molar shape evolution are slow relative to their potential.

Phylogenetic Comparative Methods for Evaluating the Evolutionary History of Function-Valued Traits.

A method for extending ancestral state reconstruction to incorporate function-valued traits in a phylogenetic generalized least squares (PGLS) framework is introduced, as well as extensions of this method for testing phylogenetic signal, performing phylogenetic analysis of variance (ANOVA), and testing for correlated trait evolution using recently proposed multivariate PGLS methods.



Phylogenies and the Comparative Method: A General Approach to Incorporating Phylogenetic Information into the Analysis of Interspecific Data

A generalized linear model (GLM) is presented for the analysis of comparative data, which can be used to address questions regarding the relationship between traits or between traits and environments, the rate of phenotypic evolution, the degree of phylogenetic effect, and the ancestral state of a character.

Procedures for the Analysis of Comparative Data Using Phylogenetically Independent Contrasts

Any (continuous) trait that is inherited from ancestors is appropriate for analysis, regardless of the mechanism of inheritance (e.g., genetic or cultural), according to Felsenstein's method.

Historical perspectives in ecology and evolutionary biology: the use of phylogenetic comparative analyses

Hypotheses about the adaptive significance of a trait have long been tested by making comparisons among species. Many recent studies emphasized that conclusions about the origin and maintenance of

Comparative Analyses of Phylogenetic Effects in the Life-History Patterns of Iguanid Reptiles

With the exception of clutch size, the results show that the phylogenetic effect on the life-history traits is largely attributable to correlation with body size, and residual variation in the remaining traits may in part represent species-specific responses to unique ecological selective regimes.

Phylogenies and the Comparative Method

A method of correcting for the phylogeny has been proposed, which specifies a set of contrasts among species, contrasts that are statistically independent and can be used in regression or correlation studies.


A phylogenetic approach was developed, overlaying the thermal data on a phylogeny of the six genera and applying a "minimum evolution" algorithm to estimate ancestral values at nodes, which concluded that thermoregulatory behavior and physiology were at least partially coadapted.


We use computer simulation to compare the statistical properties of several methods that have been proposed for estimating the evolutionary correlation between two continuous traits, and define

Brownian motion computer simulation was used to test the statistical properties of a spatial autoregressive method in estimating evolutionary correlations between two traits using interspecific comparative data, showing how diagnostic techniques can be useful in detecting and avoiding such situations, but that such techniques should not be used as definitive evidence that phylogenetic correlation is not present in a set of comparative data.

Testing Hypotheses About Evolutionary Change on Single Branches of a Phylogeny Using Evolutionary Contrasts

The method of evolutionary contrasts is extended to allow character change along a set of single branches on a phylogeny to be estimated, expected variances are presented, and it is shown that these extensions also result in aSet of contrasts that are not correlated because of common ancestry.

Truth or Consequences: Effects of Phylogenetic Accuracy on Two Comparative Methods

Simulations show independent contrasts to be valid when branch lengths are known, whether or not the topology is known fully, and how the two approaches stand up to incompletely resolved trees and incorrect branch length information—common situations for comparative biologists.
