Curated OER
Understanding Cladistics
Students explore cladistics and create a cladogram of their own. They are shown how the scientist at the American Museum of Natural History use a method called cladistics to group animals. Students are asked how the animals (lion,...
Curated OER
A Phylogenetic Perspective for the Cladistically Challenged
Students observe the structures of skulls as presented in drawings, and determine which are most closely related to the skull of the mosasaur.
Curated OER
WHAT, IF ANYTHING, IS A ZEBRA?
Students read the essay, "What, If Anything, Is a Zebra?" following a teacher made reading guide. They investigate cladistics, shared derived characteristics, with further online research to enhance their study of evolution and...
Curated OER
Cladistics Is a Zip...Baggie
Students explore how the grouping of organisms based on their shared derived characters forms the basis of a cladogram.
Curated OER
Why Cladistics?
Young scholars explore how biological classification is intimately associated with evolution.
Curated OER
A Phylogenetic Perspective for the Cladistically Challenged
Students use M&Ms to simulate radioactive decay of elements.
Curated OER
Wait, They Can do it by Themselves?
Students recognize the concepts of evolution and natural selection as well as cladistics and phylogenetics. They observe the process of regeneration in a sea anemone to simulate asexual reproduction.

AP: Chapter 25: Phylogeny and Systematics
As a review or note taking guide, this resource wraps up a unit on the tree of life. Biology bigwigs define phylogeny and answer questions about the subsequent classification of organisms. The worksheet takes a straightforward and...

Ebola: Disease Detectives
How did the Ebola virus first infect humans? Young virologists examine genetic sequences from the 2014 Sierra Leone outbreak to find similarities during a riveting activity. Following similar methods used by MIT and Harvard, partners...

What Should You Know about Classification?
Many learners have a tough time picking out pertinent information from a text or in class. Sometimes, all it takes is a study/reading guide to show them the way. The worksheet here focuses on taxonomy and classification, including...
Curated OER
Molecular Sequences & Primate Evolution: Amino Acids, Hemoglobins in Evolution
Students compare differences in amino acids in the beta hemoglobin from representative primates, complete a matrix of those differences, and from these data, construct and interpret cladograms as they reflect relationships and timing of...
Curated OER
Species Diversity and Phylogeny
Students explore the classification system of organisms: taxonomy. They examine prepared slides of Protozoans and record information on a Taxonomy Recording Sheet. Two additional classifying activities are also included in this lesson.
Curated OER
Taxonomy
In this biology worksheet, students complete a crossword puzzle with 39 questions on taxonomy. They identify the different classification systems used in biology.
Curated OER
Grouping Dinosaurs
Students investigate sets and subsets as they group coins and dinosaurs. Using scissors and provided sheet, they sort dinosaurs according to their commonalities. Their groupings are shared with the class.

Kimball's Biology Pages: Cladistics
This page discusses how the cladistic level of classification includes information from molecular biology to establish evolutionary relationships. The page discusses how this information is used to do this.

Serc: Phylogenetics Problems
A lesson plan where students solve problems by using cladistics to determine phylogenies. Problems require that students determine which characteristics are ancestral or derived by looking at both dinosaurs' remains and primate skulls....
