How Natural Selection Works in the Simulation
The simulation models natural selection by demonstrating how populations adapt over generations. Environmental pressures influence survival, reproduction, and trait distribution, illustrating evolutionary changes and species resilience.
4.1 The Process of Natural Selection
In the PhET simulation, natural selection begins with genetic variation in a population. Environmental pressures, such as predators or climate, act as selective forces. Individuals with traits better suited to their environment are more likely to survive and reproduce, passing their advantageous traits to offspring. Over generations, this leads to adaptation, as favorable traits become more common. The simulation visualizes this process, allowing users to observe how populations evolve in response to specific conditions.

This interactive approach clarifies the role of adaptation in natural selection, making complex evolutionary concepts accessible and engaging for learners of all levels.
Genetic Variation and Its Impact
Genetic variation is essential for natural selection, providing diverse traits that influence survival and reproduction. The PhET simulation demonstrates how variation arises from mutation and genetic recombination, shaping evolutionary outcomes and enabling populations to adapt to changing environments.
5.1 Sources of Genetic Variation
Genetic variation arises from mutation, recombination, and gene flow. Mutation introduces new alleles, while recombination shuffles existing ones during reproduction. These processes create diverse traits within populations, essential for natural selection. The PhET simulation illustrates how variation emerges and influences adaptation. By exploring these mechanisms, users understand the raw material driving evolutionary change. The answer key provides insights into assessing genetic diversity and its role in survival. This foundational concept highlights the importance of variation in enabling populations to respond to environmental pressures, ensuring survival and reproductive success.
5.2 Selection and Genetic Drift in the Simulation
The PhET simulation demonstrates how natural selection and genetic drift shape populations. Selection favors traits that enhance survival and reproduction, while genetic drift introduces random changes in allele frequencies. Users can observe how environmental pressures influence trait frequencies over generations. The simulation also shows how smaller populations are more susceptible to genetic drift, leading to unpredictable outcomes. The answer key provides guidance on analyzing these dynamics, helping users distinguish between the effects of selection and drift.
