Explain the implications of how adaptations can only be passed down via heredity on evolution (4 Marks)

Answer: Evolutions happens very slowly, over many many years. Someone does not just start strouting another limb or animals do not start to grow other limbs or webbed feet instantly. This happens over many years if needed, as ecosystems change. This would mean organisms would need to adapt to those changes. This can only transfer through heredity to continue the cycle, so that evolution can take place. Good Luck!
