Given : 1 = Natural selection , 2 = Variations and their inheritance , 3 = Survival of the fittest , 4 = struggle for existence
According the Darwinism, which of the following represents the correct squence of events in the origin of new species ?

Options

A. 1,2,3,4
B. 2,3,1,4
C. 3,4,1,2,
D. 4,2,3,1

Answer

To determine the correct sequence of events in the origin of new species according to Darwinism, we can break down the concepts involved:

1. **Struggle for Existence (4)**: This is the initial stage where organisms compete for limited resources such as food, space, and mates. This struggle is a fundamental aspect of natural selection.

2. **Variations and Their Inheritance (2)**: Within a population, individuals exhibit variations in their traits. These variations can be inherited from one generation to the next, which is crucial for evolution.

3. **Survival of the Fittest (3)**: In the context of the struggle for existence, those individuals with advantageous traits are more likely to survive and reproduce. This concept is often summarized as "survival of the fittest," where "fittest" refers to those best suited to their environment.

4. **Natural Selection (1)**: This is the process through which the traits that enhance survival and reproduction become more common in the population over generations. Natural selection acts on the variations present in the population.

Now, putting these steps together, the correct sequence according to Darwinism is:

- **Struggle for Existence (4)**
- **Variations and Their Inheritance (2)**
- **Survival of the Fittest (3)**
- **Natural Selection (1)**

Thus, the correct order is 4, 2, 3, 1.

### Final Answer:
The correct sequence of events in the origin of new species according to Darwinism is: **4, 2, 3, 1**.
