Grade 9 Evolution
Animal behaviors can evolve through natural selection because
  1. all behavior is completely the result of genes.
  2. what an animal learns is incorporated into its genes.
  3. all behavior is completely the result of environmental influences.
  4. genes that influence behavior that increases an individual's fitness can be passed onto the next generation.
Grade 9 Evolution
Which statement is most commonly associated with Darwinism?
  1. Survival of the Weakest
  2. Organisms adapt to the environment
  3. Survival of the Strongest
  4. Survival of the Fittest
Grade 9 Evolution
Because of its similarities to artificial selection, Darwin referred to the "survival of the fittest" as
  1. homologous structures.
  2. struggle for existence.
  3. natural selection.
  4. use it or lose it.
Grade 9 Evolution
Who is renowned as the Father of Evolution?
  1. Gregor Mendel
  2. Charles Darwin
  3. Jean Baptiste Lamarck
Grade 9 Evolution
The scientific theory that populations change over time is known as
  1. adaptation.
  2. evolution.
  3. natural selection.
  4. transition.
Grade 9 Evolution
The book written by Charles Darwin proposing his theory of evolution is called
  1. The Selfish Gene.
  2. Origins of Evolution.
  3. Evolution by Natural Selection.
  4. On the Origin of Species by Natural Selection.
Grade 9 Evolution
What is the evolutionary history of an organism or group?
  1. natural selection
  2. classification
  3. phylogeny
  4. taxonomy
Grade 9 Evolution
Which statement 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 the genetic diversity of a population.
  4. Gene flow is another form of evolution alongside natural selection that results in the change of a population due to certain alleles moving in or out of a population.
Grade 9 Evolution
What mechanism of evolution is best represented here in this image of the Lynx?
  1. Adaptations, specific traits that are beneficial.
  2. Non-random mating
  3. Population change
  4. Movement, immigration flow
Grade 9 Evolution

  1. USS Evolutionist
  2. HMS Beagle
  3. SS Alvin
  4. SS Discovery
Grade 9 Evolution
What is speciation?
  1. a population or group of populations whose members can interbreed and produce fertile offspring
  2. two or more species reproducing at one time
  3. a species migrating to a new area
  4. formation of a new species
Grade 9 Evolution
On the Galapagos Islands, Darwin observed that the characteristics of many animals and plants
  1. all looked alike.
