Crash Course Zoology - Season 1 Episode 1 第 1 集 ()

In the inaugural episode, we endeavor to answer just what an animal is, because as it turns out, it’s complicated! But before we get there we’ll need to introduce you to zoology more broadly, tell you about taxonomy (the branch of science dedicated to naming and describing organisms), and then we’ll get to phylogenetics (which looks at traits, evolutionary history, and relationships among living things).
