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 ?
(a) 3,4,1,2
(b) 2,3,1,4
(c) 1,2,3,4
(d) 4,2,3,1

Options

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

Answer

To determine the correct sequence of events in the origin of new species according to Darwinism, we need to analyze the given options based on the principles of natural selection.

1. **Struggle for Existence (4)**: This is the first step in Darwin's theory. Organisms must compete for limited resources, which leads to a struggle for survival.

2. **Variations and their Inheritance (2)**: After the struggle, variations arise among individuals within a species. These variations can be inherited by the offspring, which is crucial for evolution.

3. **Survival of the Fittest (3)**: In this context, "fittest" refers to those individuals who are better adapted to their environment due to the variations they possess. These individuals are more likely to survive and reproduce.

4. **Natural Selection (1)**: Finally, natural selection is the process through which the environment "selects" the individuals that are best suited to survive and reproduce, leading to the evolution of species over time.

Putting this all together, the correct sequence of events according to Darwinism is:
- Struggle for existence (4)
- Variations and their inheritance (2)
- Survival of the fittest (3)
- Natural selection (1)

Thus, the correct option is **(d) 4, 2, 3, 1**.
