Grade 9 :: Evolution by McBobbo
Which of the following early hominids was the first to leave Africa?
  1. Homo Habillis
  2. Homo Erectus
  3. Homo Sapiens
  4. Homo Neanderthalensis
Grade 9 :: Evolution by McBobbo
Which of the following statements regarding evolution is false?
  1. Genetic drift due to a drastic reduction of population size is called the Bottleneck Effect. This type of genetic drift decreases the genetic diversity of a species.
  2. Sexual selection is a form of natural selection in which certain organisms will be selected over others based on certain traits.
  3. Disruptive selection occurs when a genotype is completely removed from a population, causing a drop in genetic diversity of a population.
  4. Gene flow is another form of evolution alongside natural selection which results in a change in a population due to certain alleles moving in or out of a population.
Grade 7 :: Evolution by mtn2ocean
A change that increases an organism's chances for survival is called a:
  1. adaptation
  2. mutation
  3. radiation
  4. homologous structure
Grade 7 :: Evolution by mtn2ocean
Another way to say, "Survival of the Fittest" is:
  1. natural selection
  2. overproduction
  3. adaptive radiation
  4. mutation
Grade 7 :: Evolution by mtn2ocean
In the theory natural selection, species are most likely to survive if they:
  1. inherit acquired traits
  2. have variations that make them adapted to their environment
  3. overproduce
  4. are isolated
Grade 7 :: Evolution by mtn2ocean
Young embryos of different vertebrates
  1. have acquired traits
  2. have no similarities
  3. have similarities
  4. are called homologous embryos
Grade 10 :: Evolution by Drv00d00
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 7 :: Evolution by mtn2ocean
A bat's wing and a lion's leg bones are examples of:
  1. variation
  2. homologous structures
  3. migratory effects
  4. fossils
Grade 7 :: Evolution by mtn2ocean
Which of these is NOT used as evidence of evolution?
  1. fossils
  2. embryos
  3. niche
  4. homologous structures
Grade 7 :: Evolution by mtn2ocean
The survival and reproduction of organisms best adapted to their surrounding is called:
  1. evolution
  2. reproductive advantage
  3. adaptation
  4. natural selection
Grade 8 :: Evolution by sharrik
Different kinds of plants living in the same area must compete for water. Which plant represents "survival of the fittest"?
  1. the plant with the largest leaves
  2. a plant with a compact root system
  3. the plant with the largest root system
  4. a plant with needles instead of leaves
Grade 10 :: Evolution by MarcBeinder
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 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 because of the water quality
Grade 10 :: Evolution by MarcBeinder
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
