Using Amino Acid Sequences to Show Evolutionary Relationships
Junior biologists compare the amino acid sequences from fragments of five different globin molecules. They count the letter differences between each species pair. They construct a graphic representation of the evolutionary relationships...
Curated OER
Tree of Life
Students study genetics and evolution. They evaluate a group of organisms and estimate their genetic relatedness. Then they use an online program to check the accuracy of their estimations and make a branching phylogenetic tree which...
Curated OER
Vertebrate Dioramas
Students describe the development of their chosen form of vertebrate life from the past to the present in a four to six page paper. They explain the use of a phylogenetic tree, and use this to exemplify an organism's evolutionary change...
Curated OER
Constructing a Phylogenetic Tree Using DNA Sequence Data
Students analyze DNA sequence differences between organisms in order to establish a reasonable picture of the evolutionary relationships between them. They take the role of molecular biologists and make genetic changes and constructing...
Curated OER
Cut-Off Genes
Students explain the concept of gene sequence analysis. In this gene lesson, students draw inferences about phylogenetic similarities of different organisms.

Island Biogeography and Evolution: Solving a Phylogenetic Puzzle With Molecular Genetics
Students engage in solving a logic problem based on real organisms and real data. They develop phylogenies for seven related populations of lizards living on the Canary Islands.
Curated OER
Playing Hot and Cold
Students read about homeothermy. Through research and poster projects, they gain insight into the diversity among mammals and the ways specific mammals survive in their native climates.

Applied Evolution: How Will We Get There from Here?
Students explore the basic process of natural selection and how people can manipulate that process today. The consequences of natural selection on daily life and the implications of evolutionary biology in basic and applied science is...
Curated OER
Determination of Phylogenetic Relationships Using Restriction Analysis
Pupils 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
Studying Species By Examining the Evolution of the Canidae Family
Young scholars read an article on the characteristics of wolves and dogs then complete a phylogenetic tree of the canid family. They then write an essay justifying why or why not wolves and dogs should be classified as different species.
Howard Hughes Medical Institute
Using DNA to Explore Lizard Phylogeny
In a fun and interactive two-day lesson, learners sort anole lizard pictures by appearance. Next, they watch a video about the anoles and re-sort based on the information in the video. In addition to physical characteristics, budding...
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
Studying Species by Examining the Evolution of the Canidae Family
Students examine the definition of species. Students complete a phylogentic tree of the Canidae family. They write an essay justifying why or why not wolves and dogs should be classified as different species.
Curated OER
Anolis Lizards of the Greater Antilles
Students "take a trip" to the Greater Antilles to observethe Anolis lizards. They study the body structures and habitat of different species, then plot this data on a map to look for patterns in their distribution. From the patterns they...
