Aim To integrate ecological fitting, the oscillation hypothesis and the taxon pulse hypothesis
into a coherent null model for the evolution of complex host–parasite associations. Location …

Coelurosauria is the most diverse clade of theropod dinosaurs. Much of this diversity is
present in Paraves—the clade of dinosaurs containing dromaeosaurids, troodontids, and …

To better determine the history of modern birds, we performed a genome-scale phylogenetic
analysis of 48 species representing all orders of Neoaves using phylogenomic methods …

Background Integrated, efficient, and global prioritization approaches are necessary to
manage the ongoing loss of species and their associated function." Evolutionary …

The phylogeny and divergence timing of the Neoavian radiation remain controversial
despite recent progress. We analyzed the genomes of 124 species across all Neoavian …

Secondary aquatic adaptations evolved independently more than 30 times from terrestrial
vertebrate ancestors,. For decades, non-avian dinosaurs were believed to be an exception …

Ratites are large, flightless birds and include the ostrich, rheas, kiwi, emu, and cassowaries,
along with extinct members, such as moa and elephant birds. Previous phylogenetic …

The most comprehensive account of the origin of ancient and modern birds—the" living
dinosaurs." A small set of fossilized bones discovered almost thirty years ago led …

Well-preserved fossils of pivotal early bird and nonavian theropod species have provided
unequivocal evidence for feathers and/or downlike integuments. Recent studies have …

In this complete and thorough update of Arthur Boucot's seminal work, Evolutionary
Paleobiology of Behavior and Coevolution, Boucot is joined by George Poinar, who …
