The best definition of natural selection is:
Correct answer: B. The process by which individuals with advantageous traits are more likely to survive and reproduce
- A. Survival of the fittest
- B. The process by which individuals with advantageous traits are more likely to survive and reproduce
- C. Those who eat better, are healthier, and live longer are the most fit within a population
- D. Preservation of traits that lead to increased survival and reproduction
Explanation
Natural selection is a fundamental mechanism of evolution, where individuals with traits that enhance their ability to survive and reproduce are more likely to pass those traits to subsequent generations. The correct option accurately describes this process by emphasizing the role of advantageous traits in increasing reproductive success. Other options either oversimplify the concept to mere survival or fail to encompass the full scope of evolutionary fitness, which includes both survival and successful reproduction.

About Darwinism
Darwinism explains evolution through inherited variation, competition for limited resources, survival and reproduction of better-adapted organisms, and natural selection over generations. It is distinguished from Lamarckism because Darwin's explanation depends on selection acting on existing heritable differences, not the inheritance of acquired characteristics.
