If you’re familiar with the basics of evolution you’re probably familiar with phylogenies: the tree-like structure that allows you to tell how closely related species are. For example, here is a simply phylogeny of some groups of vertebrates:

Now watch this video to understand the motivation behind phylogenetic research and the role you can play in determining how evolution happened.
