The graph below shows the variation in average beak size in a group of finches in the Galápagos Islands over time. These finches eat mostly seeds. Use the graph to answer the question that follows.
4. Beak size in these finches is correlated to the size of seeds they can eat. What can be inferred from the graph?
F. In wet years, the finches that survive are mostly those that can eat larger seeds.
G. In dry years, the finches that survive are mostly those that can eat larger seeds.
H. In all years, the finches that survive are mostly those that can eat larger seeds.
J. In all years, the finches that survive are mostly those that can eat smaller seeds.

The human body has a tailbone but no tail. It also has an organ called the appendix, which is attached to the intestines but does not serve a function in digestion.
How would an evolutionary biologist explain the presence of these structures in the human body?

The human body has a tailbone but no tail. It also has an organ called the appendix, which is attached to the intestines but does not serve a function in digestion.
How would an evolutionary biologist explain the presence of these structures in the human body?
Answer:
The human tailbone and appendix are vestigial structures that have little or no function in human bodies, but that are very similar to structures with functional roles in other primate species.

An example of an acquired characteristic is large leg muscles built up in an individual by frequent running. An example of an inherited characteristic is the maximum height to which an individual can grow.
Part A Explain the difference between inherited and acquired characteristics.
Part B Contrast two historical theories that explained evolution, based on either acquired characteristics or inherited characteristics.

Answer:
Part A An inherited characteristic is controlled by genes and can be passed on to offspring. An acquired trait is developed or acquired during an organism’s lifetime, and cannot be passed on to offspring.

Answer:
Part B Both Darwin’s theory and Lamarck’s theory attempted to explain evolution in terms of individuals, their characteristics, and their environments. Both theories held that populations would evolve adaptations to their environments over time. Darwin’s theory was based on changes in the inherited characteristics of individuals in populations. In Darwin’s model, evolution could occur over generations. Lamarck’s theory was based on acquired characteristics in individuals that then would become inherited. In Lamarck’s model, evolution could occur within one lifetime. Darwin’s theory has gained wide scientific acceptance, whereas Lamarck’s theory has not.
