What Did the First Animal Look Like?
If you trace your way back along the tree of life, eventually you'd come face-to-face with the very first animal. But what exactly would that animal have looked like?

Cladistics Part 2: Monophyly, Paraphyly, and Polyphyly
Now that we know how to construct cladograms, we have to learn some new terminology. These are the terms monophyly, paraphyly, and polyphyly, and they help us distinguish between any old taxon and true clades. Let's learn more about...
