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.

Students observe the two major developmental pathways (protostome and deuterostome). They analyze data regarding differences in nucleotide sequences and construct a phylogenetic tree. They observe the similar evolutionary history shared...

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...

One of the most striking pieces of evidence for Darwin's Evolution of Species was his observations of finches and how their beaks differed from island to island, depending on their primary food sources. So what would happen to the theory...

Students 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 acid...

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. 

Students construct a phylogenetic tree for various automobiles and trucks after considering important characteristics of these "organisms". They work in small groups to construct the trees and complete a set of questions then they...

Students explore early hominid evolution as they analyze bones that share characteristics of both apes and humans. Students compare and contrast key skeletal differences between chimpanzees and humans. In groups, they sort and group a...

Compare what shells look like on the outside with what makes that happen on the inside. Scholars begin by sorting an various seashells by their physical characteristics into phylogenetic trees. They then conduct a DNA comparison of...

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...
