Which of the following statements best describes the overall process of descent with modification?

• A. Organisms evolve through random changes without any influence from their environment.
• B. Descent with modification refers to the process where organisms lose traits over generations.
• C. Species change over time, with favorable traits becoming more common in successive generations.
• D. All organisms remain unchanged over time, maintaining their original traits.

Answer: (C)

Verified step by step guidance

1. Begin by understanding the concept of 'descent with modification,' which is a fundamental principle of evolutionary biology. It refers to the process by which species undergo changes over generations, leading to the development of new traits.
2. Recognize that descent with modification involves natural selection, where favorable traits that enhance survival and reproduction become more common in a population over time.
3. Consider the role of environmental pressures in shaping the traits of organisms. Traits that provide advantages in a given environment are more likely to be passed on to future generations.
4. Evaluate the statement options provided. The correct description of descent with modification is that species change over time, with favorable traits becoming more common in successive generations.
5. Understand that descent with modification does not imply that organisms remain unchanged or that changes occur randomly without environmental influence. It is a process driven by natural selection and adaptation.
