Grade 10 Evolution
Evolution is the                                                                       .
  1. process of maintaining homeostasis
  2. process that results in the increase of living material in an organism
  3. process of accumulating adaptations gradually over time
  4. none of the above
Grade 10 Evolution
During a study session about evolution, one of your fellow students remarks, "The giraffe stretched
its neck while reaching for higher leaves; its offspring inherited longer necks as a result." Which
statement is most likely to be helpful in correcting this student's misconception?
  1. Characteristics acquired during an organism's life are generally not passed on through genes.
  2. Spontaneous mutations can result in the appearance of new traits.
  3. Only favorable adaptations have survival value.
  4. Disuse of an organ may lead to its eventual disappearance.
  5. If the giraffes did not have to compete with each other, longer necks would not have been passed on to the next generation.
Grade 10 Evolution
Natural selection states that individuals
  1. with adaptive traits are more likely to survive.
  2. on the bottom level of a hierarchy have the greatest reproductive success.
  3. remain unchanged over a period of time.
  4. demonstrating altruistic behavior are the ones with the most mutations.
Grade 10 Evolution
A population of salamanders that live in a river require clear, fresh water to survive. A flood causes tons of sediment to be suspended in the river. Which of these results MOST LIKELY will happen to the salamander population?
  1. The salamanders will adapt to life on land.
  2. The salamanders will move to another river.
  3. The salamanders will adapt to living in the muddy water.
  4. The salamanders will decrease in number.
Grade 10 Evolution
Which situation directly contributed to Darwin's development of the theory of evolution?
  1. the discovery of natural selection by Alfred Wallace
  2. the death of his daughter due to illness
  3. changing wing color in peppered moths
  4. studying the beaks of finches from the Galapagos
  5. the election of Abraham Lincoln
Grade 10 Evolution
The papaya mealybug is a pest that poses a threat to many tropical plants. Which fate of the mealybug would result from the inability of the species to reproduce?
  1. The species would mutate.
  2. The species would increase.
  3. The species would become extinct.
  4. The species would continue to thrive.
Grade 10 Evolution
Mechanisms of evolution include
  1. the gradualistic model and the punctuational model.
  2. adaptive radiation, co-evolution, convergent evolution, and divergent evolution.
  3. sympatric speciation and allopatric speciation.
  4. natural selection, mutations, genetic drift, and gene flow.
Grade 10 Evolution
The bird Darwin studied was the
  1. finch.
  2. mockingbird.
  3. cardinal.
  4. blue jay.
Grade 10 Evolution
How can temporal isolation lead to speciation?
  1. If two populations do not like each other, this may lead to the formation of a separate species.
  2. If two populations reproduce in different ways, this may lead them to become separate species.
  3. If two populations are separated by a geographic barrier, this will cause them to reproduce only with other members available, which may lead them to become separate species.
  4. If two populations reproduce at different times, they are unlikely to reproduce with each other, which may cause them to become separate species.
Grade 10 Evolution
Which factor does NOT support Darwin's theory of evolution?
  1. fossil record
  2. homologous structures
  3. similarities in embryos
  4. differences in plants
Grade 10 Evolution
Before and during Darwin's time, many theories of evolution had been proposed. With which theories would Darwin most likely agree?
  1. Malthus's theory that species and populations were limited by available resources, lack of resources, and competition, and that competition drove evolution
  2. Cuvier's theory of catastrophism, where abrupt changes and the survivors of those changes were not new species at all
  3. Lyell's theory of uniformity, where a steady, gradual, and lengthy molding of Earth and its species occurred
  4. Lamarck's theory that single, simple forms could become more complex in an individual and thereby cause heritable changes in the next generation
Grade 10 Evolution
What is a similar structure in different species that originated in a shared ancestor?
  1. homologous structure
  2. vestigial structure
  3. fossil
  4. population
Grade 10 Evolution
Speciation is founded on the principle of genetic mutations and                                     .
  1. documented observations of genetics.
  2. established laws of genetics.
  3. speculated genetic possibilities.
