Grade 9 Evolution
In natural selection, what determines variation?
  1. humans
  2. animals
  3. nature
  4. sunlight
Grade 9 Evolution
Which of the following statements DO NOT support the theory of natural selection?
  1. An organism's genes change during it's lifespan to adapt to the environment.
  2. There is variation in a population.

Grade 9 Evolution
Genetic analysis of very different species, such as yeast and a human, has shown an abundance of molecular similarities. What does this indicate about the relationship between all organisms?
  1. All organisms have cells.
  2. DNA travels between species.
  3. All organisms share common ancestry.
  4. Life evolved more than once on this planet.
Grade 9 Evolution
What mechanism of natural selection does this picture best represent?
  1. Most populations are stable in size except for seasons.
  2. Without checks like predators, populations would increase.
  3. Natural resources are limited.
  4. Variation is inheritable
Grade 9 Evolution
A mutation in a species is an adaptation if the mutation
  1. weakens the species.
  2. makes the species attract mates.
  3. changes the species permanently.
  4. improves Darwinian fitness (the ability to reproduce).
Grade 9 Evolution
The first organisms to live on Earth were
  1. bacteria.
  2. fish.
  3. humans.
  4. plants.
Grade 9 Evolution

  2. More offspring are produced than can possibly survive.
  3. Acquired characteristics that are inherited are the cause of evolution.
