Final answer:
Humans are not the only species that communicate vocally. Many animals use sound to communicate, but humans uniquely use complex language.
Step-by-step explanation:
It is false that humans are the only species that can communicate vocally. Many animals, such as birds, monkeys, and frogs, use sound as a form of communication. For instance, birds sing to mark their territory or attract a mate, monkeys may use vocalizations to alert others to danger, and frogs croak to find mates. However, humans are unique in their ability to use complex language to communicate a wide array of ideas, emotions, and information. This language ability is closely tied to the development of human culture and the transmission of knowledge across generations.
