The stickleback is a well-studied system in freshwater lakes, but the evolution of convergent morphotypes that occupy different positions in the water column in marine environments is less clear. An international group of scientists led by researchers at the University of Oklahoma decided to test the extent to which independent transitions from bottom to midwater habitats in marine fish species from different oceanic basins resulted in the recurrent evolution of body shape morphologies, comparable to those documented in sticklebacks.
The motivation for this study was based on the book, Wonderful Life (ca. 1989), by noted Harvard University paleontologist and evolutionary biologist Stephen J. Gould.
