Explaining broad molecular, phenotypic and species biodiversity patterns necessitates a
unifying framework spanning multiple evolutionary scales. Here we argue that although …

Plant–hummingbird interactions are considered a classic example of coevolution, a process
in which mutually dependent species influence each other's evolution. Plants depend on …

Human activity is causing wild populations to experience rapid trait change and local
extirpation. The resulting effects on intraspecific variation could have substantial …

Adaptive radiation plays a fundamental role in our understanding of the evolutionary
process. However, the concept has provoked strong and differing opinions concerning its …

Competition can result in evolutionary changes to coexistence between competitors but
there are no theoretical models that predict how the components of coexistence change …

Urbanization is changing Earth's ecosystems by altering the interactions and feedbacks
between the fundamental ecological and evolutionary processes that maintain life. Humans …

Understanding how biodiversity has changed through time is a central goal of evolutionary
biology. However, estimates of past biodiversity are challenged by the inherent …

Haemosporidians are a diverse group of vector-borne parasitic protozoa that includes the
agents of human malaria; however, most of the described species are found in birds and …

Understanding the processes that drive phenotypic diversification and underpin speciation
is key to elucidating how biodiversity has evolved. Although these processes have been …

Linking interspecific interactions (eg, mutualism, competition, predation, parasitism) to
macroevolution (evolutionary change on deep timescales) is a key goal in biology. The role …
