Curated OER
A Phylogenetic Perspective for the Cladistically Challenged
High schoolers observe the structures of skulls as presented in drawings, and determine which are most closely related to the skull of the mosasaur.
Curated OER
Why Cladistics?
Learners explore how biological classification is intimately associated with evolution.

Taxonomy
In this biology worksheet, students complete a crossword puzzle with 39 questions on taxonomy. They identify the different classification systems used in biology.

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...

WHAT, IF ANYTHING, IS A ZEBRA?
Learners 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...

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...
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
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
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.

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...
