Нужен точный перевод с понятным содержанием помогите пожалуйста !

Some animals, like dolphins or bees, have ways of communicating, but only humans like using language for fun. Some chimpanzees have learnt sign language but they can only copy language – they don’t really communicate.

Human language probably started between 40,000 and 50,000 years ago when people started to live and hunt together. However, those people didn’t speak very well – they could only use their voices like small babies.

Today, we know about 4,000 – 5,000 languages in the world. But there are probably more that we haven’t discovered yet.
