Which of the following statements is not compatible with Darwin's theory? a. All organisms have arisen by descent with modification. b. Evolution has altered and diversified ancestral species. c. Evolution occurs in individuals rather than in groups. d. Natural selection eliminates unsuccessful variations. Evolution occurs because some individuals function better than others in a particular environment.

Key Concepts

Variation

Variation refers to the differences among individuals within a population. This diversity in traits is crucial for natural selection to operate, as it provides the necessary raw material for evolutionary processes to favor certain traits over others.

Population-Level Evolution

This concept explains that evolution occurs through changes in the genetic makeup of entire populations rather than individual organisms. It emphasizes that while individuals may have variations, it is the collective shift in the gene pool that leads to evolutionary change.

Natural Selection

Natural selection is the process by which traits that improve an organism's ability to survive and reproduce become more common in a population over time. It acts on the variation present within a population, favoring those individuals best suited to their environment.

Descent with Modification

This concept refers to the idea that all living organisms share a common ancestry and have changed over time. It highlights how species have evolved by accumulating small changes through generations, giving rise to the diversity of life we see today.
