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.
