Final answer:
The main contrasts between humans and bats include their diurnal vs. nocturnal behaviors, while comparing humans to animals in literature often serves to highlight human instincts or characteristics. Examples include Jack London's stories, the utilization of anthropomorphism in poetry, and differences in sleep-wake cycles between species.
Step-by-step explanation:
The main contrasts the narrator makes between humans and bats reflect the natural differences between the two species. While both humans and bats are mammals with body hair and the ability to nurse their young, there are several contrasts in their behaviors and physiology.
One major contrast is in their sleep-wake cycles. Humans are typically diurnal, meaning they are active during the day and rest at night, whereas many species of bats are nocturnal, being active at night and resting during the day. This difference may be due to various factors including predation, resource availability, and evolutionary adaptations.
In literature, the comparison between humans and animals, including bats, often serves to highlight certain human characteristics or to draw parallels between the instinctual behavior of animals and the sometimes more complex, but still instinct-driven, actions of humans. For example, in Jack London's stories, comparisons between humans and animals can showcase how both react to their environment and reveal underlying traits or survival instincts.
In poetry, such as Wordsworth's "I wandered lonely as a cloud," the use of anthropomorphism gives human qualities to nature and can underscore the interconnectedness of all living things. By likening people to animals and bugs, the narrator invites readers to contemplate the similarities in the essence of life across different forms of existence.
