1. HAPPY WEDNESDAY Bellwork: Write down only the bolded red portion and your answer. Two species of mice live in a field in the middle of East Texas. One mouse species is WHITE with BLACK spotting. The other is BROWN with WHITE spotting. After a year, the population of white mice has dramatically decreased, while the population of the brown mice has slightly increased.

4. Essential Question How is natural selection related to adaptation and diversity? Standard B.7C - Analyze and evaluate how natural selection produces change in populations, not individuals. B.7E - Analyze and evaluate the relationship of natural selection to adaptation and to the development of diversity in and among species.

6. Natural Selection A mechanism of evolution. The process that results in the survival or reproductive fitness of an individual or group that is best adapted to their environment (survival of the fittest).

7. Evolution: Bean Lab The purpose of this lab is to introduce natural selection by adaptations by simulating the competition of different birds for a common food source. Each student will simulate different species of birds with different beak shapes. In Charles Darwin’s On the Origin of Species, he stated that individuals best suited for a specific habitat will survive and pass their favorite traits on to their offspring. In this lab, students that obtain the most food will pass their beak shape to the next generation, while the students with the least amount of food will go extinct.

8. Problem: Which bird beak is the most successful at catching prey in a certain environment? Hypothesis: Write a hypothesis predicting which type of beak (fork, spoon, knife, or fingers) will be the most successful in collecting food. fork (Person 1)knife ( Person 3) spoon (Person 2)fingers (Person 4) If the beak type is _____________, then __________________________ because _____________________________________.

9. Procedure : Students will be divided into groups of 4. Each student represents a different bird species with different shaped beaks. For the first trial, one student will represent each beak shape: fork (Person 1), spoon (Person 2), knife ( Person 3), and fingers (Person 4). Spread the beans provided in the tray in front of you. The beans represent seeds which are the birds’ food. For thirty seconds, each bird removes beans, one at a time, from the tray using only their beak (fingers, fork, spoon, or knife). A couple things that must happen: The box must remain still in the middle of the table The food must be picked up and placed in your stomach (cup) The stomach (cup) must remain on the table You cannot steal from the competition After 30 seconds, count the number of beans each species has eaten. Record the data in the data table. The bird with the least amount of beans goes extinct. That bird must change its beak shape to the one who ate the most beans. Repeat this process two more times.

12. Conclusion: Answer the following questions in complete sentences. For Questions 2-5, the whole table must agree on their final answer. Answer the questions in this order. Independently – Question #1 Person 1 – Read Question #2 Person 4 – Read Question #5 Person 3 – Read Question #3 Person 2 – Read Question #4

13. HW: Prepare a line graph. Use a different color line for each species and provide a key. -Graph Title: “Food collecting ability of four species of bean eaters.” -Y axis: # of beans collected -X axis: Trial # (represents the generations) -Lines: The graph will have 4 lines, one for each species in different colors. -Conclusion: Based on the results, describe the change in the populations over 3 generations. Explain the relationship between ability to gather food and the ability to survive.
