Students virtually analyze the pelvic structures of the threespine stickleback fish, using photographs of living fish and fossil specimens. by Debby. The only difference between the “Basic” and “Advanced” versions of the handout is that the “Basic” version does not include the parts of the lab with chi-square analyses. This armor protects ocean sticklebacks from predatory attacks. The “Teacher Materials” provides background information, tips for using the virtual lab, and an answer key for the student handouts. Initially, the stickleback population in the lake consisted mostly of fish with pelvic spines, but over 15,000 years the population changed to fish without pelvic spines.

What are possible Explain why the stickleback fish in Frog Lake are more similar to ocean and sea-run stickleback than they are to the stickleback fish in Bear Paw Lake. In this lab, students learn and apply techniques for analyzing the forms and structures of organisms — in particular, the pelvic structures of the threespine stickleback fish (Gasterosteus aculeatus), a model organism for studying evolution. It also includes supplementary resources, such as a glossary of scientific terms and a list of references. You are going to perform Experiment 2 for the Stickleback lab this week. Characterize stickleback fish according to the presence or absence of pelvic spines. Explain your answer. The ancestralforms of stickleback fish are small ocean dwellers that sport heavy armor in the form of bony plates and spines projecting from the back and pelvis. Experiment 2: Analyze Fossil Fish.
