Final answer:
Speculative common traits between the horse-spider people of Kaan and Earthlings from the story 'Zoo' include communication, environmental interaction, and social structures. These are general examples, as the actual story text is not provided for specific reference.
Step-by-step explanation:
Given the context provided, it appears this question refers to a fictional story where "the horse-spider people of Kaan" and "the people of the Earth" are compared. However, without the actual text from the story "Zoo" mentioned in the question, it's challenging to give specific examples of their commonalities. That said, if we take a broader approach based on the related information provided about humans and animals, we can extrapolate some general ideas that might be common to both the horse-spider people and Earthlings as portrayed in a fictional narrative.
Shared Traits
Horses, spiders, and humans likely share traits such as:
- Communication: Both species, as well as humans, have methods of communication among their kind.
- Environmental interaction: All species interact with and adapt to their environments, a trait necessary for survival.
- Social structures: Horses have hierarchical herds, spiders have communal behaviors in some species, and humans have complex social systems. These structures might be a common theme explored in the story.
Without direct quotes from the story "Zoo," these are speculative examples. For a precise answer, we would need to know more about the specific characteristics and plot details of both the horse-spider people of Kaan and the people of Earth as presented in the story.
