From 5 Kingdoms to 3 Domains

Just as we once referred to the USSR as a country and now there are many more, so science is changing the way we look at classifying our living things. From the time I was a kid, I knew there were 5 kingdoms:  animals, plants, fungi, and then some others..... which are protists and monerans . . . I'm sure I couldn't remember the other 2 if I weren't actually teaching!
But now scientists are creating a new grouping:  DOMAINS.  Watch my video to learn how the classification system is changing.
