Solution

No, we cannot say in evolutionary terms which among bacteria, spiders, fish and chimpanzees have a better body design. The yardstick of a better body design is incorrect because all evolutionary processes take into account the development of the suitable and workable features in its body design that helps it to survive and adapt relevant to that particular niche of a habitat. A chimpanzee is an arboreal animal with strong long limbs designed for tree-dwelling, bacteria, and an extremophile has a cell wall cover so complex that it can survive extremely harsh and inhospitable conditions. These features have evolved to suit the habitat in which the organisms live. Note that these habitats are diverse and wide-ranging. The design and adaptations that are applicable for one surrounding become irrelevant for another. So comparing body design of organisms is odious.
