Нужен точный перевод с понятным содержанием ! 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.
