In this laboratory investigation, students will use BLAST to compare several genes, and then use the information to construct a cladogram. A cladogram (also called a phylogenetic tree) is a visualization of the evolutionary relatedness of species. Figure 1 is a simple cladogram. T70 Investigation 3 Lycopodium Selaginella Isoetes
Use this bell ringer activity to have students work on word problems, equations, or practice using formulas. Grammar Skills—Like math skills, grammar skills can always use sharpening. Daily language lessons can focus on a particular skill, such as usage or mechanics, or can incorporate grammar as a whole so that students must search for errors.
Cladogram ... Cladogram phylogenies and building cladograms it is important to consider the importance of homologous and analogous, and vestigial structures. Each of these structures will help you understand whether species have shared ancestry or if similar traits evolved seperately.
