Constructing a Phylogenetic Tree Using DNA Sequence Data Simulation: <http://www.accessexcellence.org/AE/> Students exchange the DNA” with random “ancestral mutations over time and make divergences into different evolutionary A phylogenetic tree is constructed. Then, in a second part, students construct a phylogenetic tree of another group based strictly on nucleotide sequences of present-day organisms. (SP 1, 4, 5) [CR4a] 3. Evolutionary Time: The Geologic Time String <http://www.accessexcellence.org/AE> The Time String involves the use of a string. The string is 4.6 meters long, and each millimeter on the string represents 1 million years. Knots tied at distinct locations along the string represent extinctions, beginning of Eras, and so forth, in the geologic time table. (SP 7) [CR4a] 4. Practicing Biology, 3rd Edition. Activity 23.1 A Quick Review of Hardy- Weinberg Population Genetics. Alternatively, present students with Hardy- Weinberg problems from a variety of resources. Students apply the Hardy- Weinberg equation to determine frequencies of phenotypes and alleles. (SP 2) [CR4a] 5. HHMI video: Students will view the lecture on artificial selection and a class “Evolution” discussion will follow.
