question_answer 29)

In evolutionary terms, can we say which among bacteria, spiders, fish and chimpanzees have a ‘better’ body design? Why or why not?

Answer:

Evolution is the generation of diversity due to environmental selection. More and more body designs have emerged over time. Among bacteria, spiders, fish and chimpanzees, we can say that the chimpanzees have a better body design because of a more complex body design. Various organisms evolve in their own separate ways to give rise to the current forms and have a basic difference in their body design because of specialization of all types and tissues. The chimpanzees are best adapted to survive the present day conditions and have proper division of labour in their body, i.e., they have different organs for performing different vital functions inside the body. For example, respiratory, excretory, circulatory and nervous system, etc.
