- ability to defend itself
- strategy to obtain food
- number of offsprings
- dominance over other individuals

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Darwin realised that under the intense competition of members in a population, any variation which favoured survival in a particular environment would increase the individuals ability to reproduce and leave fertile off springs. While less favourable variations decrease the chance of successful reproduction. Hence, Darwin judged the fitness of an individual by reproducing ability and the number of off springs.

Evolution
Evolution is a process that occurs in changes in the genetic content of a population over time. Evolutionary change is generally classified into two: microevolution and macroevolution. The process of changes in allele frequencies in a population over time is a microevolutionary process. Three main mechanisms that cause allele frequency change are natural selection, genetic drift, and gene flow. On the other hand, macroevolution refers to change at or above the level of the species.
