f an insecticide killed all of the insect pests in a particular population, could insecticide resistance evolve in this insect population? ( Biology and Society: Persistent Pests ) Your Answer: Yes, because the insects would gradually become more resistant to the insecticide. Correct Answer: No, because there are no remaining insects in this population to pass on beneficial alleles to the next generation. No. The insecticide killed all of the insects. 2. Which of the following is a true statement about Charles Darwin? ( Charles Darwin and The Origin of Species ) Your Answer: He was the first to realize that Earth is billions of years old. Correct Answer: He proposed natural selection as the mechanism of evolution. No. Lyell realized that Earth must be very old. 3. At the time Darwin voyaged on HMS Beagle , the popularly accepted theory in Europe that explained the origin of Earth's plants and animals held that the various species __________. ( Charles Darwin and The Origin of Species ) Your Answer: had been created by divine intervention a few thousand years before Correct.

Which one of the following statements best reflects Darwin's view of human evolution? ( Charles Darwin and The Origin of Species ) Your Answer: Humans are the product of artificial selection.

Correct Answer: sedimentary rock No. This rock forms from molten lava. 6. Why is it that isolated islands, such as the Hawaiian islands, often have many endemic organisms (found nowhere else)? ( Evidence of Evolution ) Your Answer: Immigration and gene flow from other locations results in the evolution of unique species. Correct Answer: Organisms evolve in isolation because of the difficulty of genetic exchange with other populations in distant locations. No. This situation would result in more similarities between species on an island and other locations. 7. An important challenge to traditional (pre-1860) ideas about species was the observation that seemingly dissimilar organisms, such as hummingbirds, humans, and whales, have similar skeletal structures. This most directly suggested to biologists that __________. ( Evidence of Evolution ) Your Answer: dissimilar organisms might have evolved from a distant, common ancestor Correct. Similarity in characteristics resulting from a common ancestor is known as homology, and such anatomical signs of evolution are known as homologous structures. 8.
