Which of the following best describes how the structure of organic molecules reflects Darwin's theory of evolution?
A
Organic molecules are static and do not change, reflecting a fixed design.
B
Organic molecules are randomly assembled without any evolutionary influence.
C
Organic molecules are identical across all species, showing no variation.
D
Organic molecules evolve through natural selection, leading to increased complexity over time.
Verified step by step guidance1
Understand that Darwin's theory of evolution is based on the principles of natural selection, where organisms with advantageous traits are more likely to survive and reproduce.
Recognize that organic molecules, such as DNA, proteins, and other biomolecules, are fundamental to the structure and function of living organisms.
Consider how variations in organic molecules can lead to differences in traits among individuals within a population.
Acknowledge that over time, natural selection can lead to the evolution of these organic molecules, resulting in increased complexity and adaptation to the environment.
Conclude that the structure of organic molecules reflects Darwin's theory of evolution by showing how they can change and adapt over time through natural selection, leading to the diversity of life we observe today.
