Name: Date: Evolution Performance Task Artificial Selection vs. Natural Selection – Project & Research Organizer Humans have an enormous impact on our surrounding environment. In many cases we shape the evolution of species via a process we call artificial selection. You will investigate and research a common species of your choosing and how humans have shaped its evolutionary path over time. You will conduct research and organize your findings into a cohesive product. You may choose to make a power point/google slides, poster, informational brochure, or formal research document. Along with your gathered research based on the following guiding questions, your final product must include the following: 1. Image(s) or drawing(s) of your artificially selected species 2. Image(s) or drawing(s) of your species wild ancestors or closest relations 3. A cladogram or phylogenetic tree to illustrate your species and its ancestors 4. Image(s) or drawing(s) of human interaction with the species 5. Bibliography, listing the resources you used to gather your research 1. Chose a species that has undergone the artificial selection process via human interaction. Possible choices include: horses, cows, goldfish, chickens, cats, rabbits, pigs, dogs, bananas, tomatoes, carrots, corn, apples, etc. 3. What is the closest wild species or extinct ancestor to your artificially selected species? 2. Are there multiple specific variations that have been created? If so, list them. 4. Approximately how long ago did humans start using artificial selection to influence the evolution of this species? What was their purpose for doing so? Did it fill some human need? Name: Date: 5. Describe in detail the traits of the origin species. 6. What traits where selected for? Why did humans choose to accentuate these traits? 7. What traits where selected against? Why did humans choose to remove or diminish these traits? Name: Date: 8. For traits to be heritable (passed from one generation to the next) they can come from a variety of sources: (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors. Is there any information on how the manipulated traits of your species entered its population? 9. Do you think this artificially selected species could return to the wild and be able to survive and reproduce successfully? Justify your answer. 10. Imagine you were starting with the original wild species. What naturally occurring characteristics would you select for or against? Explain your reasoning. Name: Date: List all resources and websites you used (suggestion: copy and paste URL’s here): NGSS Project Standards HS-LS3-2. HS-LS4-1. HS-LS4-5. Make and defend a claim based on evidence that inheritable genetic variations may result from: (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors. Communicate scientific information that common ancestry and biological evolution are supported by multiple lines of empirical evidence. Evaluate the evidence supporting claims that changes in environmental conditions may result in: (1) increases in the number of individuals of some species, (2) the emergence of new species over time, and (3) the extinction of other species.
