7.11BC/.12A: Adaptation of Species Organisms and Environments Going to the Dogs The Problem Key Concepts Addressed 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. 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. 1.Selective breeding is also called artificial selection. Like in natural selection, a population changes over time and certain traits become more common. 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 (FAQ) about dog breeding. Performance/College & Career Readiness Goals Guiding Question How did selective breeding lead to the development of the different breeds of dogs, starting with their wolf ancestry? 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. 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. 1 7.11BC/.12A: Adaptation of Species Organisms and Environments Going to the Dogs Student Checklist Getting Started Resources Designers Dogs: Labradoodles Artificial vs Natural Selection Pet Week Dogs: Wolf, Myth, Hero, and Friend Evolution of the Dog Dog Breed Library AKC Recognized Breeds Hybrid Dogs TASK RESOURCES DUE DATE STATUS/NOTE S 1.
