Species diversification—the balance between speciation and extinction—is fundamental to
our understanding of how species richness varies in space and time and throughout the …

For five decades, paleontologists, paleobiologists, and ecologists have investigated patterns
of punctuated equilibria in biology. Here, we step outside those fields and summarize recent …

Long-read sequencing is driving rapid progress in genome assembly across all major
groups of life, including species of the family Drosophilidae, a longtime model system for …

Bacterial lineages acquire novel traits at diverse rates in part because the genetic
background impacts the successful acquisition of novel genes by horizontal transfer. Yet …

Across a variety of biological datasets, from genomes to conservation to the fossil record,
evolutionary rates appear to increase toward the present or over short time scales. This has …

Speciation research—the scientific field focused on understanding the origin and diversity of
species—has a long and complex history. While relevant to one another, the specific goals …

Theory links dispersal and diversity, predicting the highest diversity at intermediate dispersal
levels. However, the modulation of this relationship by macro-eco-evolutionary mechanisms …

The relationship between the evolutionary dynamics observed in contemporary populations
(microevolution) and evolution on timescales of millions of years (macroevolution) has been …

Dispersal is a key process in ecology and evolution. While the effects of dispersal on
diversity are broadly acknowledged, our understanding of the influence of diversity on …

Abstract Ever since the Modern Synthesis, a debate about the relationship between
microevolution and macroevolution has persisted—specifically, whether they are equivalent …
