In birds, the pelvis and femur, are involved in walking. In whales, the pelvis and femur shown in the figure below are: • Examples of fossils • Vestigial structures • Acquired traits • Examples of natural variation
Which of the following is NOT a type of isolation that could result in speciation? • Geographic • Optical • Temporal • Physical
The strongest evidence for relationships among organisms is • Amino acid sequencing • Genetic drift • Vestigial structures • Comparative anatomy
4. The four species illustrated below most likely have similar limb structure because they all: • Share a common ancestor • Use their limbs for the same functions • Occupy the same level in the food pyramid • Adapted to the same environmental conditions
5. The hypothesis that species change over time by natural selection was proposed by • James Hutton • Charles Darwin • Thomas Malthus • Alfred Wallace
6. When a species disappears from the face of the earth, it is considered which of the following? • Extinction • Temporary speciation • Embryological development • Endangered species
7. James Hutton’s and Charles Lyell’s work was important to Darwin because these scientists? • Explained volcanoes and earthquakes • Explained all geologic events on Earth • Suggested that Earth was old enough for evolution to have occurred • Refuted the work of Lamarck, which was based on misunderstandings
8. According to fossil records, horses that lived 50 million years ago were smaller, weaker, & slower than modern horses. Which process is most likely responsible for the changes which led to the increased size, strength, and speed in horses? • Commensalism • Inbreeding • Migration • Natural selection
9. Charles Darwin called the ability of an organism to survive and reproduce in its specific environment • Diversity • Fitness • Adaptation • Evolution
10. The bottleneck effect occurs when a random event suddenly kills off a significant number of individuals within a population causing a decrease in • Isolation • Genetic variation • Stabilizing selection • None of the above
