1)When evolution was first proposed, which of the following was used as evidence to support the idea? (1 point)
A)observations of nature***
B)laboratory experiments
C)extensive fossil collections
D)genetic sequences
2)How did Darwin and Lamarck differ in their thinking about change in species? (1 point)
A)Darwin thought that organisms could induce their own changes, while Lamarck thought that change could only be induced by an organism’s environment.
B)Darwin thought that change could occur in individual organisms, while Lamarck thought that change could only occur across generations.***
C)Darwin thought that genes controlled a species’ ability to survive, while Lamarck thought that genes were only one part of a species’ ability to adapt.
D)Darwin thought that organisms had to struggle to survive, while Lamarck thought that organisms could make adjustments when conditions became difficult.
3)Luther Burbank was a plant breeder who developed a strain of potato plant that produced more tubers (the part of the root that people eat) of larger size than other potato plants that were grown on farms at the time. This strain of potato was also resistant to the potato blight that had wiped out the potato crops in Ireland in the mid-1800s. How did Burbank’s process in developing this potato compare to the process of natural selection? (1 point)
A)Burbank’s process was slower.
B)Burbank’s process did not affect the genetic makeup of the potato.***
C)Burbank’s process did not place the potato plant under any type of selection.
D)Burbank’s process did not involve environmental pressures to shape the outcome.
4)Very few fossils of jellyfish or their close relatives have been found. This makes it hard to trace the evolutionary history of jellyfish using the fossil record. What explains this? (1 point)
A)Jellyfish fossils are buried deep under the ocean floor, not in land areas where scientists hunt for fossils.
B)Jellyfish have soft bodies that decay completely before fossilization can occur.***
C)Jellyfish are a relatively new species in the history of living things on Earth and do not have ancient ancestors.
D)Jellyfish fossils are likely more fragile than other types of fossils and so they degrade before they can be examined.
5)Suppose some natural disaster occurs and a species of finch is forced to relocate from its original island where it dined on cactus flowers to an adjacent island with many fewer cacti but an overabundance of orchids. What would be the immediate consequences to the species in the first month of the change? (1 point)
A)The species would change its eating habits to feed on orchids.
B)All of the members of the species would make do with the existing cacti on their new island.
C)The entire species would go extinct.
D)Most of the members of the species would die but some would survive.***
6)What evidence was found from soft tissue samples of a remarkably well-preserved Tyrannosaurus rex that provided molecular evidence linking T. rex to a chicken? (1 point)
A)Antibodies that react in a specific way with chicken proteins reacted in the same way with T. rex proteins.***
B)Oxygen was found to be essential to T. rex’s survival in the same way that it is essential to a chicken’s survival.
C)T. rex cell structure was found to be similar to the cell structure of chickens.
D)T. rex cells were found to use glucose as a source of energy just like a chicken’s cells use glucose.
