We replicated a study by Vines et al. (2016) in Bonsall Creek which studied how five traits evolved along the gradient (i.e., the shape and position of their clines). We collected from the same sites and measured the same traits in 2020. The center image is that of a stickleback embryo. The drawings in the surrounding boxes show the Pitx1 gene region and activator proteins present in the jaw, pelvis, eye, or pituitary tissues. By examining many stickleback fossils in each rock layer, Dr. Michael Bell has determined that over many generations the skeletons of stickleback living in the lake changed. In some rock layers, most of the stickleback fossils lack pelvic spines, as pictured below.

| Meaning, pronunciation, translations and examples Stickleback's crew was removed by the retriever boat and combined efforts were made by Silverstein, Sabalo (SS-302), Sturtevant (DE-239), and Greenlet (ASR-10), to save the stricken submarine. The rescue ships put lines around her, but compartment after compartment flooded and, at 1857 hours on 29 May 1958, Stickleback sank in 1,800 fathoms of water. The Stickleback can be built as an open canoe with open gunwales or as a decked canoe with sealed compartments in the ends. The compartment bulkheads lie on the same stations as the temporary molds, so you’d use 4mm marine plywood as the molds for stations #2 and #6 and epoxy them to the planking.
