प्रश्न
Can you think of reasons why more complex organisms cannot give rise to new individuals through regeneration?
उत्तर
Higher complex organisms cannot give rise to new individuals through regeneration because complex organisms have organ-system level of organization. All the organ systems of their body work together as an interconnected unit. They can regenerate their lost body parts such as skin, muscles, blood, etc. However, they cannot give rise to new individuals through regeneration.
