Regarding evolution , Darwin's explanation is that

Options

A. Certain species have " built-in" plans of evolution
B. The traits used most often persist longer
C. Progressive adaptations enable one species to have more offsprings
D. God determines which species should evolve

Answer

**Step-by-Step Text Solution:**

1. **Understanding Darwin's Theory of Evolution**: Charles Darwin proposed the theory of evolution through natural selection. This theory explains how species evolve over time through a process of adaptation to their environments.

2. **Postulate 1: Overproduction**: Darwin observed that most species tend to produce more offspring than can survive. This overproduction leads to competition for resources among individuals of the same species.

3. **Postulate 2: Struggle for Existence**: In the struggle for existence, individuals compete for limited resources such as food, space, and mates. This competition can occur both within a species (intra-specific competition) and between different species (inter-specific competition).

4. **Postulate 3: Variation and Heredity**: Within any given population, individuals exhibit variations in traits. Some of these variations are heritable, meaning they can be passed down to the next generation. These variations can affect an individual's ability to survive and reproduce.

5. **Postulate 4: Natural Selection (Survival of the Fittest)**: The individuals with traits that give them an advantage in their environment are more likely to survive and reproduce. This concept is often summarized as "survival of the fittest," where "fittest" refers to reproductive fitness rather than physical strength.

6. **Conclusion**: Darwin's explanation of evolution emphasizes that progressive adaptations enable certain species to have more offspring. The traits that are beneficial for survival and reproduction become more common in the population over time.
