Question 12 Multiple Answer Charles Darwin made some key observations that helped him formulate his hypothesis about how selective pressures from the environment might lead to adaptation and evolutionary change. Which of the following were some of his key observations? Select ALL that apply. O Individual islands within the archipelago had their own unique, and sometimes unusual species that were well adapted to that particular island's environment. O He saw 13 different types of finches that possessed beaks and diets very different to the common finch species present on mainland Ecuador. O Darwin stayed in the Galapagos Islands for many years, to directly observe how allele frequencies in different finch species changed in response to wet and dry seasons. O Different populations of giant tortoises whose shell shape and neck length helped them collect and consume specific leaves present on the different islands. O He employed Mendel's Laws of Inheritance to track how genes were passed…

QUESTION 11 You are examining a new population that has recently migrated to and colonized a new island. Which of the following characteristics would you expect to see in your population? a. The new population will likely experience genetic drift related issues related to the founder effect. b. The new population will suffer more the effects of mutation because this is a bottleneck event. c. The new population will have high levels of heterozygosity and allelic richness. d. The new population will most likely have the same allele frequencies as the original population.

Question 5 What is the point of telling the story of how the Great Auk went extinct? Although Darwin did not think extinction occurred, the Great Auk story shows that species actually can go extinct. O Although Darwin thought extinction is caused by great catastrophes unlike anything humans have ever experienced, the Auk story shows that humans (not great catastrophes) can cause extinction. O Although Darwin thought extinction is a very slow, natural process, the inevitable side-effect of speciation, the Great Auk story shows that extinction can also occur quickly, the result of human actions. In a way, humans act as a "catastrophe."
QUESTION 2 Put these events in chronological order in the process of speciation O Reproductive isolation O Loss of gene flow Evolutionary change
