They way one species evolves will affect other species around it, which is called coevolution. After all, other animals are a part of the environment that produces the stress that causes only the most fit to survive. You see this happening in predators and their prey, as they both adapt to the other's adaptations. Can you blame them? One depends on the other for food, while the latter avoids the former to just live another day.
Jaida Elcock calls these instances of coevolution "evolutionary arms races." This video gives us examples in the American cheetah, moths with audio camouflage, cuckoos that lay designer eggs, and the snake detection hypothesis, or how snakes affected the evolution of the human brain. That last one is very important to us, because we've had a fraught relationship with snakes since forever. Even Genesis tells us to avoid snakes.
