P R O B L E M B a s e d Name: L e a r n i n g The Problem In nature, organisms change through the forces of natural selection. Humans use this nature of nature and apply it through selective breeding, developing many different animal breeds and plant varieties. One of the most popular, current trends is for dog breeders to selectively breed for what s called designer dogs. They cross popular breeds to get an animal with more desirable traits. The local library wants a dog display for National Pet Week in May. Since you are the local dog trainer for the police department, they have asked you to prepare a display that answers frequently asked questions (FAQS) about dog breeding. Guiding Question How did selective breeding lead to the development of the different breeds of dogs, starting with their wolf ancestry? Mission Deliverable Your mission is to create a display for the public library for Pet Week that illustrates the development of dogs from wolves. Part of the display should includes a designer dog (one with traits you have chosen based on characteristics you desire). This part should identify the dog s parents breeds, and it should include an illustration of the offspring. Key Concepts Addressed 1. In selective breeding, the favorable traits to be passed on to the next generation are chosen by the breeder. Careful breeding of food crops like corn and wheat have resulted in plants that yield more food per acre. Selective breeding of domestic animals like dogs have led to incredible diversity from their wolf ancestors. 2. Selective breeding is also called artificial selection. Like in natural selection, a population changes over time and certain traits become more common. Performance/College & Career Readiness Goals Science Standards VI. Biology C. Evolutions and Populations 1. Know multiple categories of evidence for evolutionary change and how this evidence is used to infer evolutionary relationships among organisms. 2. Recognize variations in population sizes, including extinction, and describe mechanisms and conditions that produce these variations. 1

Did dogs come from wolves and how? 2. What were the first dog breeds? 3. How did we get so many different breeds of dogs? 4. How come some breeds of dogs have certain health problems? 5. How do you get a designer dog? 1. School Library Database 3. Internet Create your display. The display can be can be a looping slide presentation, a stand-up display, or a poster set. The display should present the answers to FAQS #1 - #4. 1. Varies, Depending on the Type of Display 3. Color Printer FINAL DUE DATE: 2
Student Checklist (continued) TASK RESOURCES DUE DATE STATUS/NOTES Research dog breeds to design your dog (think of the traits you want your dog to have) to answer FAQ #5. Create a table to show the following: Breed Name, Traits of the Breed, Undesirable Traits, Desirable Traits, and Neutral Traits. Write a brief goal that summarizes what kind of dog you want and why. 1. Varies, Depending on the Type of Display 3. Color Printer Outline a Breeding Plan by illustrating and listing the desirable traits of each parent. Set-up and present your completed display at the public library during Pet Week. This display should illustrate the development of dogs from wolves. Part of the display should includes a designer dog (one with traits you have chosen based on characteristics you desire). This part should identify the dog s parents breeds, and it should include an illustration of the offspring. 1. Completed Display FINAL DUE DATE: 3
