Organisms A, B, C, D, E, F, G, and H are newly discovered species of bacteria from deep-sea vents. You have sequenced the DNA of each organism and have isolated a region of each organism’s genome that may be promising in constructing a phylogenetic tree. Your colleague has constructed the beginning of the tree and your goal is to finish it! Use the nucleotides given to fill out the common characteristics for the organisms. Some have already been done for you!

Explanation & Answer
BIOL 1111 – NOVA The Evolution Lab
In this lab activity, you will be exploring evolution and phylogeny on the NOVA LABS website. The Evolution
Lab has two main parts: building a phylogenetic tree and exploring an interactive tree of life. You will complete
the lab online and answer the following questions for a grade.
Part 1: In your web browser, go to http://www.pbs.org/wgbh/nova/labs/lab/evolution/research#/chooser
1. Watch the Evolution 101 video. What is something new that you learned from the video? Did the
video leave you with any questions that you would like to learn about?
Evolution theory explains how the organism continues to multiply and bring new species on the planet.
