A) Cell
B) Individual
C) Population
D) Species
Correct Answer: C
Solution :
Population is the unit of evolution. The individuals of a population form a unique set of genotypes or gene pool and local environmental factors act as selective agents to alter the gene pool in ways that adapt the organisms to the local conditions. Thus each population of a species follows its own course of evolution. Individual is the unit of natural selection (survival of the fittest). Cell is the structural and functional unit of the living organism. Species is the basic unit of classification.
