When this series started, the Bradford family consisted of Tom, the father, a respected columnist for the Sacramento Register, Joan, his wife for about 25 years, and the eight children of the couple, all of them were very normal but quite independent. Unexpectedly, actress Diana Hyland died of cancer and was written off the series after 5 episodes.
Let's first take a closer look at the linguistic diversity that existed five hundred years ago. In 1500 there were probably about 7 thousand languages spoken across the earth, most still groupable into the 25 or so major families represented today.
  There are approximately 6900 languages currently spoken around the world, the majority of which have only a small number of speakers. About 4 billion of the earth's 6.5 â¦ billion people, or over 60% of the earth's population, speak one of the following 30 languages as their native tongue.t is hard to find how many languages in the world exactly but the invaluable Ethnologue quotes 6909 living languages, that's one language for every 862,000 people on Earth.
