  1. adaptive radiation: the emergence of many species each adapted to a specific ecological niche
  2. allopatric speciation: occurs when a popuation is seperated by a geographical barrier
  3. convergent evolution: independent evolution of adaptive features in different species
  4. divergent evolution: geographical and reproductive isolation of a population from the main gene pool
  5. genetic drift: a change in allele frequencies of a population due to a chance process
  6. parallel evolution: evolution of similar features not present in the ancestoral form in two or more related species
  7. polyploidy: abrupt formation of a new species form non-disjunction
  8. speciation: the formation of a new species from a single ansestoral species
  9. sympatry: when a subpopulation becomes reproductively isolated in the midst of a parent population
