SPECIATION AND MACROEVOLUTION [PDF]

open access: yesEvolution, 1982
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.

Linking population‐level and microevolutionary processes to understand speciation dynamics at the macroevolutionary scale

open access: yesEcology and Evolution, 2021
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]

open access: yesRoyal Society Open Science, 2018
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

open access: yeseLife, 2021
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]

open access: yesActa Palaeontologica Polonica, 2017
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.

Population Size and the Rate of Language Evolution: A Test Across Indo-European, Austronesian, and Bantu Languages

open access: yesFrontiers in Psychology, 2018
What role does speaker population size play in shaping rates of language evolution? There has been little consensus on the expected relationship between rates and patterns of language change and speaker population size, with some predicting faster rates ...

Macroevolution and the Fossil Record [PDF]

open access: yesEvolution, 1982
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.

Macroevolution [PDF]

open access: yes, 2015
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.
