10.7554/eLife.06813.001 The deer mouse (genus Peromyscus) is the most abundant
mammal in North America, and it occupies almost every type of terrestrial habitat. It is not …

Ecological speciation with gene flow is widespread in nature [1], but it presents a conundrum:
how are associations between traits under divergent natural selection and traits that …

Understanding how social and affective behavioral states are controlled by neural circuits is
a fundamental challenge in neurobiology. Despite increasing understanding of central …

A central challenge in biology is to understand how innate behaviors evolve between closely
related species. One way to elucidate how differences arise is to compare the development …

How evolution modifies complex, innate behaviors is largely unknown. Divergence in many
morphological traits, and some behaviors, is linked to cis-regulatory changes in gene …

Animals often adjust their behavior according to social context, but the capacity for such
behavioral flexibility can vary among species. Here, we test for interspecific variation in …

The evolution of innate behaviours is ultimately due to genetic variation likely acting in the
nervous system. Gene regulation may be particularly important because it can evolve in a …

Evolutionary biologists have long sought to understand the selective pressures driving
phenotypic evolution. While most experimental data come from the study of morphological …

While some behaviours are largely fixed and invariant, others can respond flexibly to
different social contexts. Here, we leverage the unique burrowing behaviour of deer mice (genus …
