Final answer:
The contrasts between humans and bats in 'My Life as a Bat' highlight the theme of the limitations of human perception and experience, emphasizing how there are aspects of the natural world that go beyond what humans can understand.
Step-by-step explanation:
In "My Life as a Bat," the contrasts between humans and bats serve to develop a theme about the limitations of human perception and experience. This theme is evident in how bats possess abilities that allow them to thrive in the dark, abilities that humans lack or cannot fully understand. For instance, the adaptability of some moths against predatory bats through coevolution illustrates the ongoing arms race in nature, symbolizing the vast and often incomprehensible interactions within ecosystems that are beyond human perception. Furthermore, humans, being predominantly diurnal creatures, have a limited understanding of the nocturnal world that bats navigate with ease. Through these contrasts, the author suggests that there is much in the natural world that humans do not admire or understand because it falls outside of our limited sensory experiences.
