Metrics derived from pedigrees are key to investigating several major issues in evolutionary
biology, including the quantitative genetic architecture of traits, inbreeding depression, and …

The avian bill is a textbook example of how evolution shapes morphology in response to
changing environments. Bills of seed‐specialist finches in particular have been the focus of …

Homoploid hybrid speciation in animals has been inferred frequently from patterns of
variation, but few examples have withstood critical scrutiny. Here we report a directly …

A fundamental goal in evolutionary biology is to understand the genetic architecture of
adaptive traits. Using whole-genome data of 3955 of Darwin's finches on the Galápagos …

Evolution can be predicted in the short term from a knowledge of selection and inheritance.
However, in the long term evolution is unpredictable because environments, which …

Competitor species can have evolutionary effects on each other that result in ecological
character displacement; that is, divergence in resource-exploiting traits such as jaws and …

Extreme events can be a major driver of evolutionary change over geological and
contemporary timescales. Outstanding examples are evolutionary diversification following …

Charles Darwin's experiences in the Galápagos Islands in 1835 helped to guide his
thoughts toward a revolutionary theory: that species were not fixed but diversified from their …

Adaptive radiations are prominent components of the world's biodiversity. They comprise
many species derived from one or a small number of ancestral species in a geologically …

Evolutionary rescue, whereby adaptive evolutionary change rescues populations from
extinction, is theorized to enable imperiled animal populations to persist under increasing …
