e. Fitness
1. The process through which traits become more or less common in a population due to consistent reproduction of their bearers.
2. A change in a trait that enhances an organism’s survival and reproduction in a specific environment.
3. Differences among individuals in a population that can lead to variation in traits.
4. The idea that individuals best adapted to their environment are more likely to survive and reproduce.
5. A measure of how well an organism can survive and reproduce in its environment.
2. Short Answer Questions: Respond to the following questions in complete sentences.
a. Explain how variation within a species can lead to natural selection.
b. Describe an example of an adaptation in a specific animal and how it helps the animal survive in its environment.
c. How might environmental changes affect the process of natural selection?
3. Fill in the Blanks: Use the words provided in the word bank to fill in the blanks in the following passage about natural selection.
Word Bank: mutation, reproduction, traits, resources, selective pressure
Natural selection is influenced by several factors including the availability of __________. Individuals within a species have different __________, and those with favorable conditions are more likely to survive and reproduce. Additionally, __________ can introduce new variations in a population. Over time, these factors can lead to a change in the population as certain traits are favored under __________.
4. True or False: Indicate whether the following statements are true or false.
a. Natural selection acts on individuals, but evolutionary change occurs at the population level.
b. All variations in traits are beneficial for survival.
c. Natural selection is a random process.
d. Over time, natural selection can result in a new species.
5. Case Study Analysis: Read the provided case study about the peppered moth and answer the questions below.
Case Study: The peppered moth originally had a light coloration that helped it blend into the lichen-covered trees in England. During the Industrial Revolution, soot from factories darkened the trees, making the lighter-colored moths more visible to predators. Over time, darker moths became more common due to their increased chances of survival.
a. Identify the selective pressure acting on the peppered moth population.
b. How did the population of moths change as a result of natural selection?
c. What would likely happen to the moth population if pollution levels decreased and trees became lighter again?
6. Create a Concept Map: Use the following key phrases to create a concept map illustrating the process of natural selection. Include connections between the concepts.
– Variation
– Adaptation
– Natural Environment
– Survival of the Fittest
– Reproduction

Darwin’s Natural Selection Worksheet – Hard Difficulty
Darwin’s Natural Selection Worksheet
Instructions: Complete the following exercises to test your understanding of Darwin’s theory of natural selection. Each question or activity requires critical thinking and application of concepts related to evolution.
1. Short Answer Questions: Answer the following questions in complete sentences.
a. Describe the process of natural selection and explain how it leads to evolution over time. Include at least three key mechanisms involved in this process.
b. Identify and explain the role of variation within a population and why it is essential for natural selection to occur.
c. Discuss how environmental factors can influence which traits are considered advantageous. Provide two specific examples.
2. Case Study Analysis: Read the following scenario and answer the associated questions.
Scenario: A population of rabbits inhabits a forest where the ground color varies from light tan to dark brown due to the presence of different types of soil and foliage. Over several generations, the rabbits that are darker in color seem to have higher survival rates than lighter-colored rabbits.
a. Analyze how this scenario illustrates the principles of natural selection. What selective pressures are at play?
b. If a new predator, who is more adept at detecting lighter-colored rabbits, is introduced to the environment, predict how this might affect the rabbit population in the following generations.
3. Data Interpretation: You are provided with two sets of data about two different species of finches found in the Galápagos Islands, known for their beak size related to food sources.
Species A: Average beak size: 10 mm; Primary food source: Seeds from a specific plant.
Species B: Average beak size: 15 mm; Primary food source: Hard nuts from various trees.
a. Create a table comparing the beak sizes and food sources of the two species.
b. Explain how the beak size of each species is an adaptation to their specific environment. What factors might lead to further evolutionary changes in these finch populations?
4. Critical Thinking: Write a brief essay (250-300 words) addressing one of the following prompts.
a. Evaluate the implications of human activities, such as habitat destruction and climate change, on natural selection in wildlife populations. What can be done to mitigate these effects?
