SPECIATION ASSIGNMENT Read chapter 16-3 in textbook (starts on page 404) Answer the following questions in complete sentences in your journal. 1. 2. 3. 4. 5. 6. Define the following terms (from the first 2 paragraphs or from glossary): a. Species b. Speciation Explain what it means if 2 populations are ‘reproductively isolated.’ Describe and give an example of the 3 isolating mechanisms: a. Behavioral isolation b. Geographic isolation c. Temporal isolation Apply the 5 points of natural selection to the evolution of the large beak size of the large beak ground finch pictured in chart on page 406. How/why did the finches evolve larger beaks? Include all 5 points! Summarize the research of Peter and Rosemary Grant. As stated on page 408, speciation in Galapagos finches occurred by founding of a new population, geographic isolation, changes in the new population’s gene pool, reproductive isolation, and ecological competition. Write a 1 sentence summary detailing each factor’s contribution to the process of speciation (thus you should have 5 sentences total!)
