Abstract Attempts to predict macroevolution from microevolution, and microevolution macroevolution, when natural selection is the main cause have met with varying success. Explanations for failure are numerous, but reasons uncertain even a link found. Here, I discuss possible explanations outcomes of three efforts ways test them. First, quantitative genetic variation within populations often predicts directions species divergence surprising accuracy. Natural probably contributes this pattern, evidence suggests that long-term phenotypic evolution influenced by enduring biases. Second, rate reproductive isolation repeatedly fails diversification rates unknown reasons. Suspicion falls on influence ecological population demographic processes might play dominant role in net accumulation species, an idea as yet little tested. Third, macroevolutionary patterns distribution phenotypes clades can principle coefficients diverging populations. use concept adaptive landscape suggest why signal divergent strongest at time splitting information about phylogenetic methods remains long run. Estimating landscapes first principles would facilitate further macroevolution.

3Genome and life-history evolution link bird diversification to the end-Cretaceous mass extinction

Complex patterns of genome evolution associated with the end-Cretaceous [Cretaceous-Paleogene (K-Pg)] mass extinction limit our understanding early evolutionary history modern birds. Here, we analyzed avian molecular and identified distinct macroevolutionary regimes across exons, introns, untranslated regions, mitochondrial genomes. Bird clades originating near K-Pg boundary exhibited numerous shifts in mode evolution, suggesting a burst genomic heterogeneity at this point Earth's history. These inferred substitution were closely related to developmental mode, adult body mass, metabolic scaling. Our results suggest that triggered integrated genomes, physiology, life dawn bird radiation.

2Macroevolution of body extremities reveals an integrated phenotypic response of coloration and morphology to temperature in a large clade of Neotropical passerines (Furnariida)

ABSTRACT Endotherms show smaller extremities (Allen’s rule) and larger body sizes (Bergmann’s in colder climates, thereby reducing heat loss. Coloration can also be important thermoregulation, as darker coloration absorbs more radiant energy than lighter (Bogert’s rule or thermal melanism hypothesis). Extremities lacking bearing thinner covers of feathers fur—such ears, legs bills—can windows to exchange heat. Yet, no study date has simultaneously investigated the morphology relation temperature. In 566 species Furnariida (Neotropical ovenbirds allies), we tested with phylogenetic comparative methods whether extremity coloration, plumage jointly respond We predicted that, bills tarsi would well associated sizes. Consistent this prediction, found that are darker, climates. Tarsi but tarsus is not length, which, contrary predictions Allen’s rule, was longer Using path analyses, climate affects both directly indirectly through its effects on habitat type, morphology. Our suggests temperature promotes an integrated phenotypic response across extremities, plumage, size.
