3. Self-Paced Exploration: Learners can progress at their own speed, allowing for deeper understanding and retention of material.
Natural Selection: A Fundamental Concept in Biology
Natural selection is a key mechanism of evolution that explains how species adapt over time. It operates on the principle that individuals with traits better suited to their environment are more likely to survive and reproduce.
The Process of Natural Selection
Natural selection can be broken down into several key components:
1. Variation: Within a population, individuals exhibit variations in traits (e.g., color, size, speed).
2. Overproduction: Most species produce more offspring than can survive, leading to competition for resources.
3. Struggle for Existence: Organisms compete for limited resources such as food, space, and mates.
4. Survival of the Fittest: Individuals with advantageous traits are more likely to survive and reproduce, passing those traits to the next generation.
5. Descent with Modification: Over time, favorable traits become more common in the population, leading to evolutionary change.
Examples of Natural Selection
- Peppered Moths: During the Industrial Revolution in England, the population of peppered moths shifted from predominantly light-colored to dark-colored due to pollution.
- Darwin's Finches: Different species of finches on the Galápagos Islands evolved various beak shapes to access different food sources, demonstrating adaptation to their environments.
Exploring Natural Selection with Gizmos
The Gizmo student exploration on natural selection typically includes a variety of activities that allow students to manipulate variables and observe outcomes.
Key Activities in the Gizmo Exploration
1. Simulation of Environmental Changes: Students can change environmental variables such as food availability, habitat destruction, or climate shifts to see how they affect survival.
2. Trait Variation Exercises: By adjusting the traits of organisms (like coloration or body size), students can observe which traits lead to higher survival rates in different scenarios.
3. Population Dynamics: Students can simulate populations over generations to see how traits propagate through a population over time.
