Genomic signature of an avian Lilliput Effect across the K-Pg Extinction

Survivorship following major mass extinctions may be associated with a decrease in body size-a phenomenon called the Lilliput Effect. Body size is a strong predictor of many life history traits (LHTs), and is known to...

Preliminary paleoecological insights from the Pliocene avifauna of Kanapoi, Kenya
Daniel J. Field
Mar 31, 2020

Fossil bird remains from the Pliocene hominin-bearing locality of Kanapoi comprise >100 elements representing at least 10 avian families, including previously undescribed elements referred to the ‘giant’ Pliocene marabou...

Bird Evolution

Feb 22, 2019
New fossils help pinpoint when some birds started relying on a seed-based diet and reveal that disparate bill shapes evolved repeatedly throughout bird evolutionary history.

Macroevolutionary dynamics of dentition in Mesozoic birds reveal no long-term selection towards tooth loss.
Several potential drivers of avian tooth loss have been proposed, although consensus remains elusive as fully toothless jaws arose independently numerous times among Mesozoic avialans and dinosaurs more broadly. The origin of...
The changing face of birds from the age of the dinosaurs.

The fossil record traces the origin of the modern bird skull as birds evolved from their dinosaurian ancestors. Now the discovery of a bizarre fossil reveals a surprising diversion during this process of facial transformation.
McShane on the Transformation of Botany
Daniel Mayer
Mar 16, 2022
Daniel Mayer, leadership educator and researcher into the epistemology of biology, has long reflected on the nature of organization, both of organisms and of organizations. This is the topic of his recently completed PhD...
Climatic shifts drove major contractions in avian latitudinal distributions throughout the Cenozoic.
Many higher level avian clades are restricted to Earth's lower latitudes, leading to historical biogeographic reconstructions favoring a Gondwanan origin of crown birds and numerous deep subclades. However, several such...
Disentangling the avian altricial-precocial spectrum
The altricial-precocial spectrum describes patterns of variation in avian developmental mode that greatly influence avian life histories. Appraising a given species' position on this spectrum is therefore fundamental to...
Distinct developmental pathways underlie independent losses of flight in ratites
Cynthia Faux, Daniel Field
Jul 05, 2017
Recent phylogenetic studies question the monophyly of ratites (large, flightless birds incorporating ostriches, rheas, kiwis, emus and cassowaries), suggesting their paraphyly with respect to flying tinamous (Tinamidae)....

Daniel A. Helminiak is Emeritus Professor of Psychology, University of West Georgia. He holds PhDs in theology and psychology and has published widely in these fields and their applications to spirituality and sexuality. Among...
Late Cretaceous neornithine from Europe illuminates the origins of crown birds.
Our understanding of the earliest stages of crown bird evolution is hindered by an exceedingly sparse avian fossil record from the Mesozoic era. The most ancient phylogenetic divergences among crown birds are known to have...
Localization and field-periodic conductance fluctuations in trilayer graphene

We have systematically studied quantum transport in a short trilayer-graphene field-effect transistor. Close to the charge neutrality point, our magnetoconductance data are well described by the theory of weak localization in...

The True Identity of Putative Tooth Alveoli in a Cenozoic Crown Bird, the Gastornithid Omorhamphus
All extant birds are toothless, and recent molecular evidence suggests that edentulism in extant birds is the product of a single evolutionary transition to toothlessness on the line to crown birds in the Cretaceous. However, a...
Early Evolution of Modern Birds Structured by Global Forest Collapse at the End-Cretaceous Mass Extinction

The fossil record and recent molecular phylogenies support an extraordinary early-Cenozoic radiation of crown birds (Neornithes) after the Cretaceous-Paleogene (K-Pg) mass extinction [1–3]. However, questions remain regarding...
