HS-LS4-2. 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. Evolution is a fundamental process that shapes the diversity of life on Earth. It is driven by several key factors that influence how species adapt and survive in their environments. This review sheet will explore the four primary factors contributing to evolution: the potential for population growth, genetic variation, competition for resources, and natural selection Understanding these factors helps explain how species evolve and adapt over time. Main Concepts Potential for a Species to Increase in Number:All species have the potential to reproduce and increase in number. However not all offspring will survive to adulthood due to environmental constraints. This potential for population growth is a driving force behind evolution , as it creates the opportunity for natural selection to act on variations within the population. Heritable Genetic Variation:Genetic variation arises from mutations and sexual reproduction. Mutations are random changes in DNA that can introduce new traits, while sexual reproduction shuffles genetic material, creating diverse combinations of traits These variations are heritable, meaning they can be passed on to offspring and contribute to evolutionary change. Competition for Limited Resources: Resources such as food, water, and shelter are limited in any environment. Organisms must compete for these resources to survive and reproduce This competition influences which individuals are more successful in their environment and consequently, which traits become more common in the population. Proliferation of Better-Adapted Organisms: Organisms with traits that enhance their ability to environment are more likely to pass those traits on to the next

Answer

Evolution results from species' potential to grow, genetic variation, resource competition, and survival of better-adapted organisms. Explanation 1. Identify Key Factors Evolution is driven by four main factors: potential for population growth, genetic variation, competition for resources, and natural selection. 2. Potential for Population Growth Species can reproduce rapidly, but not all offspring survive due to environmental constraints. This creates opportunities for natural selection. 3. Heritable Genetic Variation Mutations and sexual reproduction introduce genetic diversity. These variations are heritable and contribute to evolutionary change. 4. Competition for Resources Limited resources lead to competition among organisms, influencing which individuals survive and reproduce. 5. Natural Selection Organisms with advantageous traits are more likely to survive and reproduce, passing those traits to the next generation.
