According to the theory of evolution by natural selection, which of the following best explains how a population adapts to its environment over time?
A
All individuals in a population change their traits simultaneously in response to environmental changes.
B
Individuals with advantageous traits are more likely to survive and reproduce, passing those traits to the next generation.
C
Mutations always result in beneficial adaptations for the population.
D
Traits acquired during an organism's lifetime are inherited by its offspring.
검증된 단계별 안내1
Understand the theory of evolution by natural selection: This theory explains how populations adapt to their environment over time through differential survival and reproduction of individuals with advantageous traits.
Clarify the concept of advantageous traits: These are traits that increase an organism's chances of survival and reproduction in a specific environment. Such traits are often heritable and passed on to offspring.
Examine the role of genetic variation: Genetic variation within a population provides the raw material for natural selection. Mutations, genetic recombination, and other processes contribute to this variation.
Analyze the process of selection: Individuals with traits that confer a survival or reproductive advantage are more likely to pass those traits to the next generation. Over time, these traits become more common in the population.
Debunk misconceptions: Traits acquired during an organism's lifetime (e.g., learned behaviors or physical changes due to environment) are not inherited genetically. Additionally, not all mutations are beneficial; some may be neutral or harmful.
