The paper investigates stabilizing selection on Drosophila wing shape and shows it constrains macroevolutionary change despite genetic variance.

The paper experiments with Drosophila melanogaster to show that male density affects offspring recruitment, though less strongly than female density dependence.

The paper assesses sexual selection on Drosophila wing color and morphology, finding that wing size and shape explain part of wing color variation and that sexual selection acts on a combination of color and morphology.
