Recent innovations in phylogenetic comparative methods (PCMs) have spurred a
renaissance of research into the causes and consequences of large‐scale patterns of …

The Red Queen hypothesis (RQH) is both familiar and murky, with a scope and range that
has broadened beyond its original focus. Although originally developed in the …

A new species of tyrannosaurid from the upper Two Medicine Formation of Montana
supports the presence of a Laramidian anagenetic (ancestor-descendant) lineage of Late …

Abstract Ever since the Evolutionary Synthesis of the 1930s and 1940s, some biologists
have expressed doubt that the Synthetic Theory, based principally on mutation, genetic …

The long-controversial theory of punctuated equilibrium (PE) asserts that speciation causes
rapid evolution against a backdrop of stasis. PE is currently undergoing a resurgence driven …

Measuring the pace at which speciation and extinction occur is fundamental to
understanding the origin and evolution of biodiversity. Both the fossil record and molecular …

Probabilistic approaches to phylogenetic inference have recently gained traction in
paleontological studies. Because they directly model processes of evolutionary change …

Biological Essentialism addresses three main issues. The first concerns the essences
(natures, identities) of biological taxa, particularly species. Kripke and other metaphysicians …

High‐throughput sequencing approaches offer opportunities to better understand the
evolutionary processes driving diversification, particularly in nonmodel organisms. In …

Morphological stasis or the absence of morphological change is a well-known phenomenon
in the paleontological record, yet it is poorly integrated with neontological evidence. Recent …
