Biology Video: Evolution and Speciation. Learning Objectives for this video:

  • Speciation and Evolution. Learn about Speciation. Examine the theory of natural selection, and learn about gene mutation, gene flow, and genetic shift.
  • Examine allopatric speciation and instantaneous speciation involving polyploidy, and survey intrinsic reproductive isolating mechanisms that complete the divergence of genetically distinct populations by preventing crossbreeding through four different means.
  • Gain an understanding of how a population evolves as the result of changes, caused by mutation pressure, gene flow, and genetic drift, in the gene frequencies of that population.
  • Discover the many benefits of using online video for visual learning. Educational video for teaching the K-12 curriculum provides online learning for children and students of all ages and abilities. Using subtitled video - or video with closed captions - enables children to choose between watching, listening to, or reading each presentation whichever best suites their individual learning style. A wonderful option particularly for dyslexia and special needs education.
