The process that has transformed life on earth from its earliest forms to the vast diversity is:
Correct answer: B. Evolution
- A. Mutation
- B. Evolution
- C. Migration
- D. Genetic drift
Explanation
The correct answer is Evolution. It is the comprehensive process by which species of organisms develop from earlier forms through changes over long periods. It includes various mechanisms such as natural selection, mutations, genetic drift, and gene flow, all contributing to the transformation and diversification of life on Earth. Mutation, migration, and genetic drift are individual mechanisms within the broader evolutionary process, but they cannot independently account for the vast diversity of life observed today.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
