In a story set 1,000 years in the future, the evolution of animals like wolves and dogs may not show significant physical changes due to the relatively short time frame. However, behavioral adaptations could emerge as they fill new ecological niches. Potential natural enemies for humans in this scenario could include feral dogs, which are intelligent and hunt in packs, as well as large predators like big cats in certain regions. Smaller threats, such as aggressive rodents, insects, and diseases, may pose greater risks to humans than larger animals. The concept of invasive species, including adaptive insects, could also play a role in the ecosystem. The narrative suggests that in a post-apocalyptic world, humans may face more danger from other humans and competition for resources from intelligent animals like raccoons and bears, rather than from traditional predators. The lack of education and information could lead to a misunderstanding of the surrounding wildlife, heightening the sense of danger.
