Biology 16 3 the process of speciation[1]

  1. 1. 16-3 The Process of Speciation<br />
  2. 2. Speciation<br />Formation of new species<br />
  3. 3. Reproductive Isolation<br />Separation of species or populations so that they cannot interbreed and produce fertile offspring.<br />These birds do not mate because their mating songs are different<br />
  4. 4. Behavioral Isolation<br />Form of reproductive isolation in which two populations have differences in courtship rituals or other types of behavior that prevent them from interbreeding<br />
  5. 5. Geographic Isolation<br />Form of reproductive isolation in which populations are separated physically by geographic barriers such as rivers, mountains, or stretches of water.<br />Mountains<br />
  6. 6. Temporal isolation<br />Form of reproductive isolation in which two populations reproduce at different times.<br />
  7. 7. Key concept<br />As new species evolve, populations become reproductively isolated from each other.<br />
  8. 8. Key Concept<br />Speciation in the Galapagos finches occurred by founding of a new population, geographic isolation, changes in the new population’s gene pool, reproductive isolation, and ecological competition.<br />
