Evolution

Nicolas Mathevon examines the evolution of vocal communication through an analysis of songs from more than 3,000 passerine species. The study organizes their acoustic diversity into eight basic motifs and relates motif use to social organization, morphology, mating systems and sound transmission. Tropical forest conditions favor simpler signals such as flat whistles that travel effectively through dense habitat. In temperate regions, dense populations, short breeding seasons and stronger sexual selection favor complex signals such as rapid trills, despite their greater degradation during transmission. The resulting global pattern reflects a changing balance between environmental constraints and selection for complex communication. Online on 30 September 2026, 17:00–18:00 CEST (Europe/Paris; UTC+2), with an optional 15-minute discussion afterward. Open worldwide through Zoom.

This EMBO workshop brings experimental and computational researchers together around molecular mechanisms of adaptation, evolutionary dynamics, microbial communities, symbiosis, biodiversity, and cell-environment interactions.

This Lake Conference is a 3.5-day forum on comparative and evolutionary approaches to nervous-system function. The program includes invited and selected talks, poster sessions, comparative genomics and genetics, evolutionary and developmental mechanisms, and evolutionary neuroscience systems biology.

Annual meeting of the Society for Integrative and Comparative Biology at the David L. Lawrence Convention Center in Pittsburgh, PA, spanning research across integrative and comparative biology.

We have entered a golden age of artificial intelligence research, driven mainly by the advances in the artificial neural networks over the last several decades. Applications of these techniques—to machine vision, speech recognition, autonomous vehicles, natural language, and many other domains—are coming so quickly that many observers predict that the long-elusive goal of “Artificial General Intelligence” (AGI) is within our grasp. However, we still cannot build a machine capable of building a nest, stalking prey, or loading a dishwasher. I will describe how evolution may have shaped the algorithms that the brain is using to solve some of these challenging problems. Presented in the van Vreeswijk Theoretical Neuroscience Seminar series (formerly WWTNS) on 2025-05-21. Recording duration: 00:44:20.
