  • Q1
    The graph shows the number of taxa of reptiles whose fossilized tracks have been found. Which statement is best supported by these data?
    Question Image
    Environmental conditions for speciation were most favorable for reptiles during the Permian period
    A great extinction occurred during the Jurassic period
    Competition for food and shelter among reptile species was very low during the Triassic period
    Reptiles adapted to a terrestrial environment during the Cretaceous period

  • Q2
    This diagram of the fossil record represents changes in mollusks over millions of years. How can the pattern of change in the fossil record best be explained?
    Question Image
    The mollusks were well adapted to their stable environment. The mollusks hybridized with a smaller species of mollusk. A new species of mollusk with a bigger shell resulted
    The mollusks were not well adapted to their environment. The length of the mollusks’ shells changed gradually over time. The mollusks in the original population that had small shells died over a period of many years
    The mollusks were well adapted to their stable environment. A large, sudden change occurred in their environment. After the change the mollusks with the bigger shells were better adapted for the new environment
    The mollusks were well adapted to their environment. Humans introduced a new species of mollusk that was not adapted to this environment. The introduced mollusk outcompeted the native mollusk species

  • Q3
    The cladogram shows the evolution of land plants as indicated by fossil records.Which discovery would challenge the validity of this cladogram?
    Question Image
    A species of algae that has existed for less than one million years
    A fossil of a fern more than 425 million years old
    A large aquatic vascular plant about 200 million years old
    A moss species that has existed for less than 380 million years

  • Q4
    After examining the fossil record, scientists have determined that scorpions today are much smaller than their extinct ancestors. For example, Jaekelopterus rhenaniae, a giant scorpion species that lived 255 million to 460 million years ago, was 2.5 meters long. Which of the following conclusions is supported by this information?
    Scorpions living today have increased their numbers since they first appeared
    Scorpions do not appear in their original state in the fossil record
    Scorpions in the fossil record are smaller than their descendants are
    Scorpions have changed as a result of natural selection

  • Q5
    Niles Eldredge and Stephen Jay Gould researched the lenses of the eyes of fossil trilobites of different species. In 1972 they published a paper in which they described the tendency of a species to remain the same until a sudden change in the environment causes a new related species to appear. Which hypothesis was most challenged by the work of Eldredge and Gould?
    Wallace's hypothesis that geography affects the distribution of species
    Darwin's hypothesis that the development of species is a slow, gradual process
    Redi's hypothesis that spontaneous generation does not occur
    Haeckel's hypothesis that embryological development mimics the evolution of species
