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...

Young scientists use the Internet to evaluate how organisms are classified. They research the phylogeny of organisms and how they are linked in a certain way. Pupils hone research technology skills with their final presentations.

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.

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...

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...

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...

Learners 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...

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...

Young scholars 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...

Students list the morphological characters used to identify the cacti in the field, and describe the associated problems in using these characters for identification. They draw the geographical ranges of the varieties of species...

Young scholars 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...
