Why Do Animals Have Tails?

The video explores why animals have tails and humans do not. It explains that animals use tails for various purposes such as communication, balance, and flicking away flies. Dogs wag their tails to express emotions, while farm animals like horses and cows use them to swat flies. Rats and cats use tails for balance, and monkeys use them for both balance and swinging. Humans, on the other hand, do not need tails because they have other means of communication and balance.
