Why do some animals have sharper senses than humans?

Many animals have sharper senses than humans due to evolutionary adaptations that help them survive in their environments. For example, certain species of bats and dolphins have highly developed echolocation abilities, allowing them to detect objects in complete darkness or murky water. Dogs have a far superior sense of smell, which helps them detect food, danger, or specific scents, while birds of prey have exceptional vision, allowing them to spot small prey from great heights. These heightened senses increase their chances of finding food and avoiding predators.
