From Restriction Maps to Cladograms
Biology aces analyze restriction maps to determine the relationships among different primate species and then complete a cladogram. Preface this lesson with an explanation of how restriction enzymes are used to create the DNA maps....
Curated OER
From Restriction Maps to Cladograms
Pupils develop a matrix to determine the number of differences between each set of primate species. They determine closely related organisms then complete the cladogram and answer a set of questions.
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,...

Making Cladograms
Students construct cladograms (evolutionary trees), showing how shared derived characters can be used to reveal degrees of relationship. They interpret and analyze cladograms, and determine where unclassified vertebrates would fit on a...
Curated OER
Classroom Cladogram of Vertebrate/Human Evolution
Students build a Colossal Classroom Cladogram of vertebrate evolution. After putting it together, they show the gradual, mosaic accumulation of the traits which we, as humans, possess.

PRIMATE CLASSIFICATION: Evolution, Cladograms,
Students transfer examples (names) of primates from their location in an outline hierarchy of primate groups into a set of nested boxes reflecting that same hierarchy. A cladogram can then be drawn illustrating how these groups are...
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.

NOVA Evolution Lab Lesson Plan
It doesn't matter if you look on land, in the air, underground, or in water—evolution is everywhere. Scholars complete worksheets with multiple question types as they progress through six online missions creating phylogenic trees.Â
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
What did T. rex taste like?
Students examine the three domains of life and explain that all living things share a common ancestor. In this paleontology lesson students are introduced to the process of illustrating evolutionary relationships.Â
Curated OER
Spider Activities, Experiments and Projects
Young scholars examine seven spiders and put them into two or three groups based on their structural similarities. In groups, they create a cladogram proposing possible ancestral relationships. Students design an experiment related to...
Curated OER
Systematics: Classifying Organisms
Students describe the techniques biologists use to classify organisms. In this biology lesson, students create cladograms and phylogenetic trees. They list the levels of taxonomic hierarchy.
Curated OER
Molecular Approaches to Evolution
Students are introduced to working with molecular data. The first activity does both simulated and original data are used to compare amino acid, protein or DNA differences to construct phylogenetic trees or cladograms. These activities...

Taxonomy: Who is in My family?
Find similarities in seemingly unlike organisms. The second instructional activity in a series of 12 builds the concept of a taxonomy and explores the use of a dichotomous key. Learners begin in part one by attempting to group a set of...
Curated OER
Evolutionary Relationships Based Upon Comparative Genetics
High schoolers investigate the protein cytochrome c in an attempt to use its genetic chemistry to study possible evolutionary relationships between organisms. The lesson integrates technology with the use computers to perform DNA analysis.
Curated OER
Who is the Sea Otter Related to?
Students examine the genetic relationships of different organisms. In groups, they discover the importance of genes and how different amino acids show various evolutionary relationships. They use an online database to continue their...
Curated OER
Classification, Keys, and Phylogenetci Trees
Students analyze relationships about animals and create a model of classifications based on both the similarities and the differences. They also discuss a dichotomous key before they create a cladograph using different types of candy.
Curated OER
The Cytochrome-C Lab
Young scholars examine a method biologists use to try to determine relationships. They examine how amino acid sequences have been determined for a number of proteins, and how scientists can make inferences about DNA based on the amino...
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
Inside the Cranium: Neuropsychiatric Disorders
Students analyze different regions of the brain which are responsible for different aspects of cognition, awareness and regulating the body's process.
Curated OER
Molecular Approaches to Evolution
High schoolers examine the molecular studies of organisms that have led to a new era in their understanding of speciation and evolutionary relationships. Students study the allelic frequency of genes controlling specific molecules and...

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...

Why Cladistics?
Learners explore how biological classification is intimately associated with evolution.

Using Cytochrome-C to Explore Evolutionary Relationships
Students analyze protein sequences. In this instructional activity on determining evolutionary relationships, students use the Internet tools BLAST and Biology Workbench to look at protein sequences. Students will compose an essay that...
