Nervous system signal conduction is unique to animals, as it is a characteristic of their complex nervous systems, allowing for rapid communication between cells. Other options like chitin (found in fungi and some animals), heterotrophy (common in fungi and some protists as well), and flagellated gametes (seen in plants, fungi, and some protists) are not unique to animals.
