Key Protein Essential for Smell and Survival Identified

The Orco protein is crucial for the survival of olfactory neurons in ants. Mutating the orco gene in Harpegnathos saltator ants drastically reduced their number of olfactory neurons, impairing their social interactions. This stud highlights the importance of Orco in neural development and social communication in ants. Understanding these mechanisms can provide insights into sensory-mediated social behavior in both animals and humans.
