The Diversity of Language in Papua New Guinea

The word for bear in the Middle Ages was taboo because it probably came from Ursus. In China you can't say the word tiger in some places so if you're speaking about a man eating tiger you'll use a different word often referred to as big insect. The diversity of language in Papua New Guinea is extraordinary, I think it's the highest diversity in the world. So they have over 800 languages, 850 languages. There's this thing called the Greenberg's diversity index which charts how much diversity language is in per country. As Papua New Guinea holds the top spot it is so diverse there that the probability of two random people selected in the country talking to each other would be 98.8
