An Automobile Phylogenetic Tree
Learners study a list of cars and trucks and think about characteristics that can be used to show an "evolutionary relationship". From the characteristics they identity, students construct a phylogenetic tree to show how the automotive...
Curated OER
Determination of Phylogenetic Relationships Using Restriction Analysis
Students applied various mathematical analyses to interpret their data. By using the resulting DNA fragment patterns from several enzymes students established a possible evolutionary relationship among the mice.
Curated OER
Molecular Evidence for Evolutionary Relationships
Students compare the amino acid sequences in cytochrome-c for a variety of organisms and use this information to infer evolutionary relationships. Students investigate the role of homeobox genes and what this indicates about the...

Organizing Principles of Plants and Animals
Three lessons and five assessments are contained in this material. Various paper shapes are sorted as a simulation of biological classification. Learners gather a list of living things that they are familiar with and design a...
Curated OER
Molecular Biology and Primate Phylogenetics
Pairs of high school biologists compare amino acid differences in the beta hemoglobin of different primates. They use the information collected to construct a phylogenic tree. Follow-up discussion questions are provided. This is a...

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.
Curated OER
Investigating Evolutionary Questions: Bats, Whales, Reptiles, Birds, Animal Classification
Students are guided through a process in which three questions are addressed by retrieving beta hemoglobin sequences from online databases, and using online tools to compare those sequences in student-selected animals.
