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

The concept of evolvability emerged in the early 1990s and soon became fashionable as a
label for different streams of research in evolutionary biology. In evolutionary quantitative …

Heritable variation is a prerequisite for evolutionary change, but the relevance of genetic
constraints on macroevolutionary timescales is debated. By using two datasets on fossil and …

Biodiversity is defined by trait differences between organisms, and biologists have long
sought to predict associations among ecologically important traits. Why do some traits trade …

Understanding the causes and limits of population divergence in phenotypic traits is a
fundamental aim of evolutionary biology, with the potential to yield predictions of adaptation …

Modularity is now generally recognized as a fundamental feature of organisms, one that may
have profound consequences for evolution. Modularity has recently become a major focus of …

The degree to which developmental biases affect trait evolution is subject to much debate.
Here, we first quantify fluctuating asymmetry as a measure of developmental variability, ie …

Following decades of intensive study, Anolis lizards have emerged as a biological model
system. We review how new research on anoles has advanced our understanding of …

Environmentally induced phenotypes have been proposed to initiate and bias adaptive
evolutionary change toward particular directions. The potential for this to happen depends in …

Macroevolutionary biologists have classically rejected the notion that higher-level patterns of
divergence arise through microevolutionary processes acting within populations. For …
