LS4A - Evidence of Common Ancestry and Diversity
In this video Paul Andersen describes several types of evidence for common ancestry. This evidence is contained in the fossils, embryos and molecules of living organisms. Even though life on our planet is incredibly diverse there are...

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 and...

Classification of Life
Paul Andersen explains the current classification system that we use in Biology. He starts with a brief history of taxonomy. He explains how the goal of classification is to reflect evolutionary relationships. He then explains how each...
Crash Course
Taxonomy: Life's Filing System - Crash Course Biology
Hank tells us the background story and explains the importance of the science of classifying living things, also known as taxonomy.

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.

Advanced Genetics
Paul Andersen explains important concepts that can not be explained by simple Mendelian genetics. He begins with a discussion of polygenic inheritance and uses a simulation on height to show how a bell shape curve of phenotypes is...

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...
Journey to the Microcosmos
Trying to Make Sense of This Overwhelming World
The goal of phylogenetic trees is to track the organisms we know of through their place in evolution.
