Peppered Moth Simulation (38-40) Analysis Questions: What do the two different backgrounds represent? What did he experiment show about how prey are selected by predators? Did your experiment support your hypothesis? If the cutouts represented moths, what moth coloration is best adapted for a dark (newspaper) background? How do you know? What data from your experiment can you use to support your answer? Are the light and dark colored moths different species? How can you tell? (think about the definition of a species) How might the gene for dark coloration in the peppered moth have originated? How does the percent of prey-recovered compare between the two different backgrounds? How does the data you collected in the experiment compare to the data from the 10-year study?

Peppered Moth Simulation (38-40) Conclusion: Write a 5 sentence summary that includes the following items; a) what the experiment tested and showed, b) how the experiment relates to natural selection, and c) how the experiment is an example of evolution. The peppered moth simulation that was performed today tested how ________________________. It showed how _______________________________. The experiment relates to natural selection because ___________________. This is an example of evolution because ___________________. So over time the moth population would change because an organisms phenotype determines ___________________________________________ in their environment.

Notes: Speciation (41)

What is speciation? Q: What’s a species? A: A group of organisms that mate and produce fertile offspring. Speciation: To form new species

Why is species diversity important? Greater diversity  greater survival in a changing environment

What must happen for new species to form? Reproductive Isolation: When 2 organisms cannot mate and produce fertile offspring.

What are the 3 types of reproductive isolation? Behavioral Isolation: Differences in courtship (seek the favor of) rituals, mating season, etc..

What are the 3 types of reproductive isolation? 2. Geographical isolation: Organisms are separated by geographically barriers (rivers, mountains, valleys, etc.)

What are the 3 types of reproductive isolation? 3. Temporal Isolation: Reproduce at different times

How can humans affect speciation? ARTIFICIAL SELECTION Custom breeding of animals based on desired traits STERILE (cant’ reproduce)

Reproductive Isolation Tri-fold Take a piece of white paper and fold into 3 columns Label one column: behavioral isolation, geographical isolation, and temporal isolation For each one draw and color a picture of it happening (refer pg. 404-405) On the back side explain how each of your pictures represent that term.

Exit Ticket: At the bottom of today’s notes: Write in 2 complete sentences what was the purpose (essential question) for today’s lesson.

Homework One page reasearch: ALL HAND WRITTEN NO TYPED PAPER Look up and find real world examples of reproductive isolation.
