Abstract  Ever since Eldredge and Gould proposed their model of punctuated equilibria, evolutionary biologists have debated how often this model is the best description of nature and how important it is compared to the more gradual models of evolution expected from natural selection and the neo‐Darwinian paradigm. Recently, Cubo proposed a method to test whether morphological data in extant ratites are more compatible with a gradual or with a speciational model (close to the punctuated… 

Ratite nonmonophyly: independent evidence from 40 novel Loci.

The results strongly support the recent molecular studies, revealing that the deepest branch within Palaeognathae separates the ostrich from other members of the clade, rather than the traditional hypothesis that separates the tinamous from the ratites.

Experimental systematics: sensitivity of cladistic methods to polarization and character ordering schemes

The results of simulations of the evolution of phenotypic traits under a Brownian motion model are presented to characterize differences in sensitivity between parsimony and 3ta to outgroup branch length, which affects the reliability of ancestral character state estimates, (2) character state ordering scheme, and (3) ingroup branch lengths that reflect the geological age of studied taxa.

Evolutionary mode routinely varies among morphological traits within fossil species lineages

Recent studies have revitalized interest in methods for detecting evolutionary modes in both fossil sequences and phylogenies. Most of these studies examine single size or shape traits, often

The effect of parity on morphological evolution among phrynosomatid lizards

The results suggest that the passage of shelled eggs constrains the morphology of the pelvic girdle, but the conclusion that transitions to viviparity increase both lineage and morphological diversification is concluded.

Bio-Connections Between Southern Continents: What is and What is Not Possible to Conclude

Characters of the South American avian fossil record are presence of taxa with uncertain affinities and the absence of Passeriformes during the Paleogene; progressive and accelerated increase of species starting at the Neogene (Miocene); and predominance of the zoophagous birds in all the associations under scrutiny.

Transposable elements and viruses as factors in adaptation and evolution: an expansion and strengthening of the TE-Thrust hypothesis

The hypothesis is expanded to more fully account for the contribution of viruses to TE-Thrust and evolution, and the possibility of punctuated episodes of speciation events and evolutionary transitions, coinciding with, and heavily underpinned by, intermittent bursts of TE activity is suggested.

South American and Antarctic Continental Cenozoic Birds: Paleobiogeographic Affinities and Disparities

Several advances have been made on the understanding of the biotic and environmental history of South America and Antarctica including the discovery of additional fossil sites coupled with progress

Evidence for speciational change in the evolution of ratites (Aves: Palaeognathae)

This method is applied to a dataset from ratites and concludes that, for a range of morphological features, change tends to have been speciational rather than gradual.

Punctuated equilibria: the tempo and mode of evolution reconsidered

It is argued that virtually none of the examples brought forward to refute the model of punctuated equilibria can stand as support for phyletic gradualism; many are so weak and ambiguous that they only reflect the persistent bias for gradualism still deeply embedded in paleontological thought.

Using Phylogenies to Test Macroevolutionary Hypotheses of Trait Evolution in Cranes (Gruinae)

A novel phylogenetic approach to the study of trait evolution is presented, employing a method that avoids point estimates of ancestor reconstructions and considers a new nonhistorical model in which changes are completely independent of history, such that differences among species are expected to be the same, regardless of relationship.

Phylogenomic evidence for multiple losses of flight in ratite birds

A phylogenetic analyses of 20 unlinked nuclear genes reveal a genome-wide signal that unequivocally places tinamous within ratites, making ratites polyphyletic and suggesting multiple losses of flight.

Character optimization, permutational multiple linear regressions, and independent contrast analyses show that Cope's rule of phyletic size increase applies to early reptiliomorphs but that it does not apply to early stegocephalians globally.

ADAPTIVE CONSTRAINTS AND THE PHYLOGENETIC COMPARATIVE METHOD: A COMPUTER SIMULATION TEST

It was found that correlations estimated without taking phylogeny into account were often quite poor and never substantially better than those produced by the other tested methods, while Felsenstein's independent contrasts (FIC) method gave the best performance in many cases, even when weak constraints had been acting throughout phenotypic evolution.

The evolutionary radiation of modern birds (Neornithes): reconciling molecules, morphology and the fossil record

Current understanding of the early fossil history of Neornithes is highlighted in conjunction with available phylogenetic resolution for the major extant clades, as well as recent advancements in genetic methods that have constrained time estimates for major evolutionary divergences.

New morphological evidence supports congruent phylogenies and Gondwana vicariance for palaeognathous birds

A morphological phylogeny based mainly on new characters from the tongue apparatus and cranial osteology, with a theoretical ancestor as outgroup is reported, fully consistent with a Gondwana vicariance model of evolution.

ACCURACY OF ESTIMATED PHYLOGENIES: EFFECTS OF TREE TOPOLOGY AND EVOLUTIONARY MODEL

The results suggest that the great majority of estimated phylogenetic trees are likely to be quite inaccurate; they underscore the inappropriateness of characterizing current phylogenetic methods as being for reconstruction rather than for estimation.
