  4. evolution.
Grade 8 Evolution
Grade 9 Evolution
Which statement about evolution is not accurate?
  1. Species share common ancestors.
  2. Evolution can be a result of natural selection.
  3. One species changes into another (monkey into man).

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.
