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

Answer:-

In evolutionary terms, we can not say which among bacteria, spiders, fish and chimpanzees have a ‘better’ body design.The notion of Better body design among different species is not justifiable. Because evolutionary process takes into account the development of most efficient and suitable features in body designs of organisms for survival and adaptation favoring to a particular niche. For example, organisms with Complex and seemingly better body design, may not survive particular situation. Where as, organisms like bacteria with its primitive body design and simple microbial life form may survive in the most inhospitable and extreme environmental conditions that are extraordinarily hot, cold or acidic. Bacterial microbes can be found everywhere — deep under polar ice, in deserts, around volcanic eruption on earth surface or thermal vents under deep sea or over earth surface, or even in outer space.
