Question

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

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

Answer 1

The correct option is D $4,2,3,1$

1. There is a struggle for existence, because of the disparity between the number of individuals produced by reproduction and the number that can survive.
   
2. Individuals within a species show variation; no two individuals are exactly alike. Those with advantageous characters have a greater probability of survival, and therefore of reproducing, in the struggle for existence.
   
3. Individuals produce offspring that tend to resemble their parents (the principle of inheritance). Provided that the advantageous characters that promote survival are inherited by offspring.
   
4. The offspring that evolve according to the condition are fittest for survival.
5. Those are selected by nature and weaker ones got eliminated.

So the correct option is '4,2,3,1'
