Which of the following correctly states the relationship between monkeys and humans?
A. Humans and monkeys evolved from apes.
B. Humans evolved from monkeys.
C. Humans and monkeys evolved from the same ancestor, which is now extinct.
D. Humans evolved from apes and monkeys evolved from a small mammalian ancestor, which is now extinct.
Under which of the following conditions will speciation not occur?
A. Logging operations in a forest cut a single population of beetles in two so that they can no longer mix.
B. Some snails in a population develop shells that twist to the right instead of the left, which makes mating impossible with partners of opposite shell shape.
C. A newly constructed housing development divides the habitat of a bird species in two, forcing the birds to fly from one section to the other.
D. Some females of a species of spider prefer to mate with males that have red markings while other females prefer to mate with males with no markings.
Luther Burbank was a plant breeder who developed a strain of potato plant that produced more tubers 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?
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.
How did Lamarck and Darwin differ in their thinking about species?
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.

Darwin thought that organisms had to struggle to survive, as Lamarck thought that organisms could just make adjustments anytime.
