We don’t notice them much today because there aren’t many left, but before colonization, North America was home to hundreds of millions of these furry engineers. This week, we show you why Earth’s second largest rodent is more amazing than you ever knew, and why they’re the smartest thing in fur pants.

SUBSCRIBE! ►► http://bit.ly/iotbs_sub ↓ More info and sources below ↓ Some people try to attack things like evolution by natural selection and man-made climate change by saying “Oh, that’s just a THEORY!” Yes, they are both theories. Stop saying it like it’s a bad thing! It’s time we learn the difference between a fact, a theory, a hypothesis, and a scientific law.

    How Many Species Are Out There?

    Viewers like you help make PBS (Thank you 😃) . Support your local PBS Member Station here: https://to.pbs.org/PBSDSDonate How do we protect what we don’t know exists? Don’t miss the next video! SUBSCRIBE! ►► http://bit.ly/iotbs_sub ↓ More info and sources below ↓ How many species are there on Earth? In biology, this is one of a fundamental question that we still don’t have a very good answer for. Imagine if chemists didn’t know all the elements of the periodic table, or if physicists didn’t know all of the particles of the standard model. Knowing how many different species there are is information we need to know in order to protect the environment, but it’s a lot harder than you think!
