solution:

In evolutionary terms, all of the organisms we see now evolved over millions of years because they were fitter and better than their forefathers. They’ve all evolved in response to the habitats they live in or the ecological roles they play. Bacteria, for example, is a relatively simple unicellular organism that can live under severe environments and proliferate rapidly to increase its population. On the other hand, a more sophisticated organism, such as a chimpanzee, requires a longer length of time to reproduce and expand its population size, despite having a stronger body or limbs.

As a result, it will be erroneous to say which organism among bacteria, spiders, fish, and chimps has a ‘superior’ body design from an evolutionary standpoint. Each of these organisms is superior to the others in one way or another. Each one is ecologically significant due to their position in the food chain and the habitat in which they have developed.
