Natural Selection
Natural Selection
How can genetic variations of traits in a population increase some individuals’ probability of surviving and reproducing in a specific environment?
Critical Thinking: Students analyze how genetic variations contribute to the survival and reproduction of individuals in specific environments.
Adaptive Perseverance: Students explore complex examples of natural selection and adaptation, developing a deep understanding of evolutionary processes.
Collaboration: Students work in groups to research and present examples of genetic variation influencing survival and reproduction, fostering a collaborative learning environment.
What is genetic variation, and how does it occur?
How does natural selection act on genetic variations within a population?
Can you provide examples of genetic variations that have led to increased survival and reproduction in specific environments?
Students will explain the concept of genetic variation and its sources.
Students will understand how natural selection acts on genetic variations to influence the evolution of populations.
Students will identify real-world examples where genetic variation has led to increased survival and reproduction.

MS-LS3-1: Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism.
MS-LS4-4: Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment.
