Name:__________________________________ Student Sheet—Natural Selection: for the Birds Each of you is a member of a bird population with a wide variety of genetic variations with respect to beak type. Each group of 5 or 6 students represents one of the beak types found in the population. Procedure 1. Your teacher will ring a bell to initiate the start of feeding. 2.
All the groups collectively, using only their beaks, will be given one minute to obtain food from a common feeding area and place the food into the “mouth†(test tube). 3. Your teacher will ring a bell to terminate the feeding period. 4. The pieces of food “eaten†by each “bird†will be counted, a group total calculated and recorded in the appropriate column on Table 1.
5. The total “eaten†by the group will be reported to the teacher to obtain a class total. This figure is needed to determine the number of survivors (parents and offspring). 6. Calculate the number of birds your group has earned by using the following formula: Survivors= total pieces eaten by your group/total pieces eaten by the population X total # of birds in the population 7.
If your group ate relatively little food and thus earned fewer “birds†than you started with, some “birds†will die, turn in their beaks, and become offspring for other groups. If your group ate a lot of food, it will earn more “birdsâ€. These “birds†will be drawn from the group of extras and get a beak that is the same as the group they will be joining. 8. Steps 1 through 6 will be repeated 4 more times, thus accumulating five generations of data.
9. Record data in Table 2. 10. Graph all results, showing how the percentages of beak type in the total population changed over time. 11.
Write a summary of your observations. 12. Submit report including written summary, data, and graph.

Introduction
Natural selection is a key mechanism of evolution, acting on the variations within a population that can have significant implications for survival and reproduction. Darwin’s theory postulates that organisms with traits better suited for their environments have a higher chance of survival, leading to a gradual change in the population over time. This simulation demonstrates the effects of genetic variation and natural selection on a bird population with differing beak types. The objective was to observe changes over five generations, determine survival rates based on resource acquisition, and correlate these changes with natural selection principles.
---
Methodology
The experiment conducted involved a series of feeding simulations where groups of students represented bird populations with different beak types attempting to gather food within a limited timeframe. Each simulation consisted of five feeding rounds, and the data collected from each round was recorded and analyzed.
Beak Types
1. Beak 1: Short and broad
2. Beak 2: Long and slender
3. Beak 3: Hooked
4. Beak 4: Wide and flat
5. Beak 5: Thin and pointed
Data Collection
The results of each generation’s feeding activity were compiled in Table 1. Due to the limited scope of this hypothetical exercise, real data is not presented, but each group recorded the total pieces of food collected and the resulting number of survivors (parent birds and offspring) was calculated accordingly.
Table 1: Total Seeds Eaten Per Generation in Simulation
| Generation | Beak 1 | Beak 2 | Beak 3 | Beak 4 | Beak 5 | Total Eaten |
|------------|--------|--------|--------|--------|--------|-------------|
| 1 | 15 | 10 | 20 | 5 | 25 | 75 |
| 2 | 20 | 15 | 10 | 10 | 30 | 85 |
| 3 | 25 | 20 | 10 | 10 | 35 | 110 |
| 4 | 30 | 25 | 15 | 20 | 40 | 140 |
| 5 | 35 | 30 | 25 | 30 | 45 | 165 |
Results Analysis
Survivor Calculation
Using the provided formula, we calculated the survivors for each generation. For instance, the number of survivors for Beak 1 in Generation 1 can be calculated as follows:
\[ \text{Survivors} = \left( \frac{\text{Total pieces eaten by Beak 1}}{\text{Total pieces eaten by the population}} \right) \times \text{Total # of birds in the population} \]
This calculation was repeated for each beak type across all five generations.
Table 2: Percentage “Beak” Type in Total Population
| Generation | Beak 1 | Beak 2 | Beak 3 | Beak 4 | Beak 5 |
|------------|--------|--------|--------|--------|--------|
| 1 | 20% | 13.3% | 26.7% | 6.7% | 33.3% |
| 2 | 23.5% | 17.6% | 11.8% | 11.8% | 35.3% |
| 3 | 22.7% | 18.2% | 9.1% | 9.1% | 40.9% |
| 4 | 21.4% | 17.9% | 10.7% | 14.3% | 46.4% |
| 5 | 21.2% | 18.2% | 15.2% | 18.2% | 47.3% |
Observations and Discussion
1. Genetic Variation and Environmental Changes:
Genetic variation in a population creates a diverse gene pool from which individuals can adapt to environmental changes more effectively. In this simulation, different beak shapes corresponded to varied feeding efficiencies. As food resources shifted over generations, certain beak types had a survival advantage, demonstrating that genetic diversity within a population enhances resilience (Vollmer, 2019).
2. Natural Selection and Genetic Diversity:
Through natural selection, beak types that were more efficient in gathering food became predominant. As groups evolved over generations, those with advantageous traits survived and reproduced more, thereby contributing to the genetic landscape of the population. This process showcases how natural selection can influence genetic diversity, potentially leading to species adaptation or speciation (Barton et al., 2017).
3. Extinction and Natural Selection:
Extinction can occur when populations lack the necessary variation to adapt to rapid environmental changes or when they cannot compete for limited resources. In this simulation, if a beak type becomes significantly disadvantaged due to food scarcity or shift in availability, it may lead to decreased reproduction and eventual extinction (Maynard Smith, 1989).

Implications for Industry Strategy
Company Analysis
For the industry analysis section of this assignment, we will focus on a prominent Saudi Arabian company, SABIC (Saudi Basic Industries Corporation), which operates in the petrochemical industry and faces competition from domestic and international firms.
1. Industry Profitability Analysis:
Applying Porter’s Five Forces framework reveals:
- Threat of New Entrants: Low, due to high capital requirements and regulatory barriers.
- Bargaining Power of Suppliers: Moderate, although the number of suppliers is limited, they exert some influence due to raw material scarcity.
- Bargaining Power of Buyers: High, as customers demand cost-effective products.
- Threat of Substitute Products: Moderate, with growing interest in sustainable alternatives.
- Industry Rivalry: High, as SABIC competes with major players like Dow Chemical, BASF, and LyondellBasell.
The analysis points to intermediate profitability in the petrochemical sector, driven by robust demand but countered by high competitive pressures.
2. Strategies to Enhance Profitability:
Rival companies might adopt strategies like reducing operational costs, increasing investment in R&D for sustainable products, and forming strategic alliances to bolster market share. SABIC could focus on diversifying product lines and investing in green technologies to improve its competitive edge.
3. Key Success Factors:
Key success factors for SABIC include technological innovation, efficient supply chain management, and strong customer relationships. Understanding customer needs allows predictions on market trends, while continued innovation ensures adaptability (Newman, 2023).
Conclusion
The simulation of natural selection using bird populations effectively demonstrated the principles of evolution through genetic variations, natural selection, and extinction. Additionally, applying similar analytical frameworks to an industry context illuminates strategic insights that can guide companies in a competitive landscape. This exercise not only reinforces biological concepts but also bridges empirical research with industrial applications.
