Final answer:
Evolution mechanisms such as mutation, genetic drift, gene flow, and natural selection drive genetic variation and adaptation, shaping the diversity of life on Earth.
Explanation:
Evolution Mechanisms: How They Enable Change
Introduction: Evolution occurs through various mechanisms that act over generations. The key mechanisms include mutation, genetic drift, gene flow, and natural selection, enabling organisms to adapt to their environments.
Body/Content:
- Mutation: Introduces new genetic variation.
- Genetic Drift: Leads to random allele frequency changes.
- Gene Flow: Causes allele distribution shifts due to migration.
- Natural Selection: Favors beneficial traits, promoting survival and reproduction.
Conclusion: These forces of evolution interact to drive genetic variation and adaptation, shaping the diversity of life on Earth.
