In studying the mating rituals of fruit flies, scientists may have learned something about how brains evolve

Summary

Nutrition label

80% Informative

Researchers identify how the architecture of brain circuits helps different species flexibly adapt to new mating signals across evolutionary timeframes.

Study is the first to describe how diverse species of fruit flies plug new sensory inputs into a set of basic brain circuits without needing to develop new neural pathways from scratch.

The findings offer a larger framework for understanding how brain wiring can change to influence behavioral evolution.

"By examining neural circuits through the lens of evolution, we hope to shed light on which neural motifs can change and how they can be altered, not through the ravages of disease, but as a consequence of evolutionary selection."
