Understanding the mechanisms underlying species formation and differentiation is a central
goal of evolutionary biology and a formidable challenge. This understanding can provide …

We investigated whether celebrated cases of evolutionary radiations of passerine birds on
islands have produced exceptional morphological diversity relative to comparable-aged …

The mechanisms of insular evolution and speciation and their impact on the world's
biogeography and biodiversity in general and on birds in particular have been central to …

While reinforcement may play a role in all major modes of speciation, relatively little is
known about the timescale over which species hybridize without evolving complete …

What explains why some groups of organisms, like birds, are so species rich? And what
explains their extraordinary ecological diversity, ranging from large, flightless birds to small …

Matsubayashi and Yamaguchi (2022) review our understanding of the adaptive and non-
adaptive causes of radiations—defined as bursts of lineage splitting generating unique …

What's so special about the birds of Hawaii? Hawaiian birds are unique, with most kinds
found nowhere else on earth, and they offer some of the best examples of adaptive radiation …

A recurring feature of oceanic archipelagos is the presence of adaptive radiations that
generate endemic, species-rich clades that can offer outstanding insight into the links …

Birds have been numerous on the earth since Cretaceous times, and the evolution of new
forms has occurred continuously. As unoccupied habitats and niches within these habitats …

Adaptive radiation is one of the most important outcomes of the process of evolution, and
islands are places where it is best observed. The term itself was first used by HF Osborn in …
