In what ways are the mockingbirds found on various islands within the Galapagos Archipelago different? B. How does the long-term observation of finches on Daphne Major on the Galapagos Islands support the theory of natural selection? 4. Natural Selection: o Make a graph of the following data, then determine which type of selection you are seeing. o What type of selection is displayed (disruptive, directional or stabilizing)?

Source is “Ricklefs, The Economy of Nature o Under data set, choose 20; groups, choose 2. o The Group 1 Label should be “Before Selection;" Group 2 Label should be “After Selection.” Pick your desired colors. o Enter data from the list below. Item name is the beak size (mm), the first value is before selection and the second is after selection. o Click next. Choose your desired font. Click next again. o Download your graph of the chart as jpg, save it to your computer, and then insert it below. Graph goes here-delete this text box. 5. Read The Conversation - Here's how scientists are tracking the genetic evolution of COVID-192 and answer the below questions. A. Which virus (SARS-COV-2 or seasonal flu) appears to be mutating faster? B. Which virus (SARS-CoV-2 or seasonal flu) has a longer genome? C. Explain the relationship between mutation rate of a virus to vaccine production (see the last paragraph of the article).
