QUESTION 14 Darwin’s finches on the Galapagos Islands are a group of species of finches. One of the major features noted is the variation in beak depth. We spent some time talking about the variation in the ground finch population and how that changed overtime and how that change corresponded to changes in environmental conditions, which affected food item characteristics and abundance. The changes in beak depth over time is a result of… a. natural selection b. gene flow c. sexual selection d. artificial selection
QUESTION 8 Morphological differences are abundant among many species. We make assumptions about why adaptations exist, but to understand whether a specific trait is a adaptive and why, researchers must create experiments that have all the following, EXCEPT: a. replication of each treatment to ensure reliability of results. b. hypotheses that are testable and falsifiable. c. include control groups. d. exceedingly small sample sizes in each treatment group. e. experimental design that enables all full interpretation of differences.
QUESTION 17 The current rate of extinction is ____ , compared to the historical background extinction rate. a. almost 1,000 times lower b. slightly less c. about the same d. up to 1,000 times higher e. fluctuating wildly
QUESTION 16 You are examining a beloved population of trillium in the backyard of your childhood home. You recall as a child that flowers were bright white. As you return to the population you note that many (but not all) of the flowers have a faint purple vertical stripe in the middle of each petal. List each of Darwin’s postulates and what must be true about your population if it has undergone evolution by natural selection for petal color.
