Scientists have long wondered whether evolution would follow the same path if history had a chance for a “do-over.” New research suggests that it does, when it comes to the brain and its regulation of ...

Researchers at University of Tsukuba have demonstrated, through multi-agent simulations in a two-dimensional space, that the combination of environmental variability and human migration may foster the ...

The study found that bird species who nest in tree cavities have independently evolved heightened aggression across lineages, particularly in females. Scientists have long wondered whether evolution ...

Scientists are the first to identify large-scale differences between surface fish and cavefish populations of A. mexicanus, as well as between different populations of cavefish. They used whole-brain ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Behavior is central to interactions with the environment and thus has significant consequences for individual fitness. Sexual selection and demographic processes have been shown to independently shape ...

A simple neural change alters mating preferences in male butterflies, aiding rapid behavioral evolution, researchers report. A simple neural change alters mating preferences in male butterflies, ...

CBT is an evidence-supported treatment for adult ADHD. Evolving trends in CBT have already improved adult ADHD treatment, and ...

Evolutionary scientists confront a paradox. Animals must benefit from current opportunities to survive, whether to feed, to evade predators, or to mate. Yet, the process of genetic adaptation is ...

SPECIES STATUS OF THE RED-SHOULDERED BLACKBIRD (AGELAIUS ASSIMILIS): IMPLICATIONS FOR ECOLOGICAL, MORPHOLOGICAL, AND BEHAVIORAL EVOLUTION IN AGELAIUS - Estatus de Especie para Agelaius assimilis: ...
