The process of adaptive radiation—the proliferation of species from a single ancestor and
diversification into many ecologically different forms—has been of great interest to …

Alpine plant radiations are compared across the world's major mountain ranges and shown
to be overwhelmingly young and fast, largely confined to the Pliocene and Pleistocene, and …

Despite tremendous efforts in the past decades, relationships among main avian lineages
remain heavily debated without a clear resolution. Discrepancies have been attributed to …

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

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 …

People depend on benefits provided by ecological systems. Understanding how these
ecosystem services–and the ecosystem properties underpinning them–respond to drivers of …

Recent phylogeographic studies have overturned three paradigms for the origins of marine
biodiversity.(i) Physical (allopatric) isolation is not the sole avenue for marine speciation …

Species richness varies widely across extant clades, but the causes of this variation remain
poorly understood. We investigate the role of diversification rate heterogeneity in sha** …

Speciation generally involves a three-step process—range expansion, range fragmentation
and the development of reproductive isolation between spatially separated populations …

Replicate radiations provide powerful comparative systems to address questions about the
interplay between opportunity and innovation in driving episodes of diversification and the …
