Amongst all the organisms given, since all are well adjusted in their specific niches, so it can't be said as to which has a better body design. A simple bacteria can survive in thermal vents to polar region. so they are all evolved organisms, some are more recent, while some more ancient.

Species is defined as group of individuals that can interbreed. All human beings are Homo sapiens and are capable of interbreeding inspite of some differences. Thus they are said to belong to same species

Preserved traces of living organisms are called fossils. Fossils found closer to the surface of earth are more recent in origin than the fossils we find in deeper layers.

Analysis of the organ structure in fossils allows us to make estimates of how far evolutionary relationships go, e.g,. presence of feathers in some fossil dinosaurs indicates that birds are closely related to reptiles.

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

No, though the function of wing in both the cases is same but their structural plan and origin is different.
