Since the early 1990s, ecologists and evolutionary biologists have aggregated primary
research using meta‐analytic methods to understand ecological and evolutionary …

Darwin's theory of sexual selection fundamentally changed how we think about sex and
evolution. The struggle over mating and fertilization is a powerful driver of diversification …

A focus on novel, confirmatory, and statistically significant results leads to substantial bias in
the scientific literature. One type of bias, known as “p-hacking,” occurs when researchers …

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

A major reimagining of how evolutionary forces work, revealing how mating preferences—
what Darwin termed" the taste for the beautiful"—create the extraordinary range of ornament …

Ecologically mediated selection has increasingly become recognised as an important driver
of speciation. The correlation between neutral genetic differentiation and environmental or …

Sexual selection has manifold ecological and evolutionary consequences, making its net
effect on population fitness difficult to predict. A powerful empirical test is to experimentally …

Observer bias and other “experimenter effects” occur when researchers' expectations
influence study outcome. These biases are strongest when researchers expect a particular …

There is much in common between the aim and tools of the quantitative geneticist and the
comparative biologist. One of the most interesting statistical tools of the quantitative genetics …

The aesthetic preferences of potential mates have driven the evolution of a baffling diversity
of elaborate ornaments. Which fitness benefit—if any—choosers gain from expressing such …
