Students will learn step by step how to read a phylogenetic tree. Phylogenetic trees are difficult for many students to understand. The way trees are drawn has very specific implications and students often struggle with determining relationships between organisms in different parts of the tree. I designed this to really help students break it down!

There are 3 parts.

The first part has two pages: a reading and then a question page. This page focuses on the nodes and branches of the trees and determining the common ancestor of organisms.

The second part discusses outgroups and in-groups. The reading and questions are on one page.

The third part discusses clades. The reading and questions are on one page.
