Grade 10 Evolution
Grade 11 Evolution
Speciation
  1. occurs at such a slow pace that no one has ever observed the emergence of new species.
  2. occurs only by the accumulation of genetic change over vast expanses of time.
  3. must begin with the geographic isolation of a small, frontier population.
  4. and microevolution are synonymous.
  5. can involve changes to a single gene.
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
