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...

Island Biogeography and Evolution: Solving a Phylogenetic Puzzle With Molecular Genetics
High schoolers 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.

All in the Family: Calculating Cousins
Students view pictures of distant "cousins" to humans. They place them in order by their distance from humans. Students receive a packet of six pages featuring graphics and a cousins summary page. They work in groups to complete 5 cousin...
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...

Applied Evolution: How Will We Get There from Here?
Pupils 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...

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...

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...

Studying Fossils
Learners compare and contrast key skeletal differences between chimpanzees and humans: brain size, teeth, hand and thumb, trunk, pelvis, lower limb, foot and big toe. They then sort and group a set of mixed "fossil bones" of chimpanzee...
