Study Notes
- Speciation is the formation of new species from existing ones.
- This can occur due to accumulation of variations, physical barriers, genetic drift, natural selection, and migration.
- Variations are differences between individuals of the same species.
- Accumulation of variations over generations can lead to new species.
- Physical barriers can separate populations and produce variations that lead to new species.
- Genetic drift caused by natural calamities or introduction of new members can produce new variations.
- Natural selection favors individuals with useful variations that can adapt to the environment.
- Only those organisms survive and produce variations that can adapt to the environment.
- Migration to a new environment can lead to new variations and new species.
- Speciation is a complex process influenced by multiple factors.
