Biology Video: Evolution - Sources of Variety Part 2

Biology Video: Evolution - Sources of Variety Part 2. Learning Objectives for this video:

• Genetic Variety. Study Sources of Variety. Learn about the theory of natural selection, and learn about gene mutation, gene flow, and genetic shift.
• Survey two sources of genetic variability in a population: mutation, which introduces new alleles, and the recombination of alleles through sexual reproduction.
• 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.
