SPECIATION AND MACROEVOLUTION [PDF]
Species and higher taxa represent, phenomenologically, two very different levels in the hierarchical organization of the living world. Ever since there has been a concept of evolution, there has been the problem how one can get from the species level to that of the higher categories.

Although speciation dynamics have been described for several taxonomic groups in distinct geographic regions, most macroevolutionary studies still lack a detailed mechanistic view on how or why speciation rates change. To help partially fill this gap, we

Dietary specialization is linked to reduced species durations in North American fossil canids [PDF]
How traits influence species persistence is a fundamental question in ecology, evolution and palaeontology. We test the relationship between dietary traits and both species duration and locality coverage over 40 million years in North American canids, a ...

Evolution of brilliant iridescent feather nanostructures
The brilliant iridescent plumage of birds creates some of the most stunning color displays known in the natural world. Iridescent plumage colors are produced by nanostructures in feathers and have evolved in diverse birds.

The completeness of the fossil record of plesiosaurs, marine reptiles from the Mesozoic [PDF]
Plesiosaurs were a highly successful group of marine reptiles occurring worldwide in the Jurassic and Cretaceous, but to date few studies have focused on their preservation through time.

Macroevolution and the Fossil Record [PDF]
The past few years have been marked by enlivened controversy about the tempo of evolution, the legitimacy of the concept of macroevolution, and the history of these and related questions. At the core of the debate is what has become known as punctuational evolution.

This book is divided in two parts, the first of which shows how, beyond paleontology and systematics, macroevolutionary theories apply key insights from ecology and biogeography, developmental biology, biophysics, molecular phylogenetics and even the sociocultural sciences to explain evolution in deep time.
