Evolutionary basis of intermale sexual behavior by multiple pheromone switches in Drosophila

Youcef Ouadah, Thomas H. Naragon, Hayley Marie Smihula, Emily L. Behrman, Mohammed A. Khallaf, Yun Ding, David L. Stern, Joseph Parker, David J. Anderson

The paper identifies pheromonal changes in Drosophila species that drive intermale sexual behavior and prevent hybridization with sibling species.

Evolution of connectivity architecture in the Drosophila mushroom body

Kaitlyn Elizabeth Ellis, Sven Bervoets, Hayley Marie Smihula, Ishani Ganguly, Eva Vigato, Thomas O. Auer, Richard Benton, Ashok Litwin-Kumar, Sophie Jeanne Cécile Caron

The paper compares connectivity patterns in the Drosophila mushroom body across species to show how evolutionary changes in neuronal connectivity relate to chemical ecology.

Mushroom body input connections form independently of sensory activity in Drosophila melanogaster

Tatsuya Tatz Hayashi, Alexander John MacKenzie, Ishani Ganguly, Kaitlyn Elizabeth Ellis, Hayley Marie Smihula, Miles Solomon Jacob, Ashok Litwin-Kumar, Sophie Jeanne Cécile Caron

The paper shows that mushroom body input connections in Drosophila form without sensory activity, suggesting genetic programming over experience-based wiring.
