    What unexpected observation helped lead Darwin to develop the theory of natural selection?

    Organisms on the Galapagos were similar to, yet different from, one another and from similar species in South America.

    Charles Darwin was influenced by Charles Lyell, who proposed that geological processes had reshaped Earth over long periods of time. Which unexpected finding during Darwin's voyage supported Lyell's ideas?

    Fossils of ocean organisms high in the Andes Mountains.

    Why did the work of James Hutton influence Charles Darwin's later ideas?

    Hutton proposed that Earth was much older than was previously believed.

    The best definition of natural selection is:

    The greater survival and reproduction of organisms with favorable variations than of organisms with unfavorable organisms.

    A company develops a pesticide that kills 95% of all roaches it is sprayed on. If this pesticide is used commercially over an extended period of time, what will most likely occur?

    The effectiveness of the pesticide will decrease over time due to natural selection.

    What does the principle of descent with modification imply?

    That all organisms descended from a common ancestor.

    Evolution can be defined as any change in the relative frequency of alleles in the gene pool of a:

    Population.

    How do fossils provide evidence of relatedness between ancient ancestors and modern species?

    By showing how widely-separated organisms have similar features.

    Which of the following provided evidence that led many scientists to accept Darwin's theory of natural selection instead of earlier theories?

    Similarities among embryos.

    On what characteristic of an organism does natural selection exert pressure?

    Phenotype.

    A dark fur mutation in a mouse population. The chart shows how the population changed over 30 generations. Which statement MOST likely explains the change shown in the chart?

    Dark mice are harder for predators to see.

    Genetic drift is most likely to result when a single population splits in two and:

    One of the population is very small.

    There are two main causes of genetic variation. Gene shuffling during meiosis is one. What is the other?

    Mutation in sex cells.

    What can a study of hox genes reveal about the evolution of a group of animals?

    How genetic changes can produce a new body.

    After an Earthquake, a river changes its course and travels through the habitat of a ground-dwelling beetle, splitting the population in two. Over time, the two populations develop different adaptations and become two species. This is an example of:

    Geographic isolation.

    Two organisms are said to belong to different species if they:

    Cannot mate and produce fertile offspring.

    How did the development on sexual reproduction affect evolutionary change?

    It sped up evolutionary change by increasing genetic variation.

    According to fossil records, the horses lived 50 million years ago were much smaller, weaker and slower than modern horses. Which process is most likely responsible for the changes that have led to the increased size, strength , and speed in horses?

    Evolution by natural selection.

    If all of the finches share a recent common ancestor as shown in the diagram, what was the final mechanism that separated them into different species?

    Geographic isolation.

    The scientific theory of evolution is supported by different types of evidence. The diagrams below show the skeletons of two different animal species. How does comparing the skeletons of these animals provide support for the scientific theory of evolution?

    It shows possible common ancestry between organisms.

    Which of the following can be determined by observing the embryos shown in the diagram?

    The organisms share a common ancestry.

    Over time, the climate of an island became drier, which resulted in changes to the population of various island finch species. Finch populations with a certain beak shape thrived, while those not having the beak shape decreased. Which of the following describes a necessary condition for these changes in the finch populations to occur?

    Limited food resources.

    Which of the following best illustrates natural selection?

    An organism with favorable genetic variations will tend to survive and breed successfully.
