Amoeba Sisters
Intro to Cladograms and Phylogenetic Trees
Join the Amoeba Sisters as they introduce the basics about cladograms and phylogenetic trees. The Amoeba Sisters walk through the process of building a basic cladogram and mention vocabulary such as: shared ancestral character, shared...

Comparing DNA Sequences
Paul Andersen shows you how to compare DNA sequences to understand evolutionary relationships. He starts with a brief introduction to cladograms and evolutionary relationships. He shows you how to classify DNA relationships using a...
Bozeman Science
Cladograms
Paul Andersen shows you how to construct a cladogram from a group of organisms using shared characteristics. He also discusses the process of parsimony in cladogram construction. He then explains how modern cladograms are constructed...
Bozeman Science
Phylogenetics
Paul Andersen discusses the specifics of phylogenetics. The evolutionary relationships of organisms are discovered through both morphological and molecular data. A specific type of phylogenetic tree, the cladogram, is also covered.
Curated Video
Interpreting a Cladogram
“Interpreting a Cladogram” will define and explain how to read a cladogram so that the student can tell how closely living things are related.

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...

Cladistics Part 1: Constructing Cladograms
Before we dive into learning about all the different kinds of animals, we have a little bit of work to do. How do we describe the relationships between animals? How does phylogeny work? We have to learn about cladistics, which means we...

Cladograms
No, a cladogram is not a new mass measurement beyond kilo. In the video, scholars watch as a simple cladogram is constructed consisting of seven organisms with shared characteristics. From this, the instructor asks where a new organism...

LS4A - Evidence of Common Ancestry and Diversity
Need help putting together an uncommonly good unit about common ancestry? Check out a video that covers NGSS standard LS4A, Evidence of Common Ancestry and Diversity. Topics include ways to convey similarities and differences between...

Comparing DNA Sequences
Through the mapping of the DNA of songbirds, scientists have discovered a gene network common among the species. In the video, scholars explore the comparison of DNA sequences, then attempt to place DNA sequences on a cladogram. They see...
