The bottleneck effect is an example of genetic drift, where a population's size is drastically reduced, altering gene frequencies.

Mutation introduces new genetic variations, which can contribute to evolutionary change.
Ref: NCERT Class 12 Biology Chapter 6: Evolution Mechanism of Evolution - Hardy-Weinberg and Natural Selection
Mutation is one of several mechanisms of genetic variation, including recombination and gene flow.
Ref: NCERT Class 12 Biology Chapter 6: Evolution Mechanism of Evolution - Hardy-Weinberg and Natural Selection
Natural selection suggests that individuals with favorable traits are more likely to survive and reproduce, contributing to evolutionary changes.
Ref: NCERT Class 12 Biology Chapter 6: Evolution Mechanism of Evolution - Hardy-Weinberg and Natural Selection
Genetic drift, especially in small populations, causes random changes in gene frequency that can lead to speciation.
Ref: NCERT Class 12 Biology Chapter 6: Evolution Mechanism of Evolution - Hardy-Weinberg and Natural Selection
Genetic recombination increases genetic diversity, contributing to evolutionary processes.
Ref: NCERT Class 12 Biology Chapter 6: Evolution Mechanism of Evolution - Hardy-Weinberg and Natural Selection
Mutation is not the only factor influencing genetic variation; recombination, gene flow, and genetic drift also contribute.

Mutation introduces new genetic variations by altering DNA sequences.
Ref: NCERT Class 12 Biology Chapter 6: Evolution Mechanism of Evolution - Hardy-Weinberg and Natural Selection
Lamarck's theory proposed the inheritance of acquired traits, not natural selection.
