Tetrapods Relatives Use this interactive “tree of life” to find organisms living today that are most closely related to these earliest tetrapods: 1. Click on this link: https://www.onezoom.org/life.html/@=304358?img=best_any&anim=flight#x1463,y672,w0.3 927 2. Locate and click on the circle labeled “Eukaryotes 1500 Ma”. Then zoom out a bit. Note the branch split at this circle divides organisms into “Diphoda” and “Amorphea”. Follow the Amorphea branch outward until you find the circle labeled “Animals” and click on that. 3. You may need to zoom out a bit to look for the circle labeled “Vertebrata”. Zoom in on that circle until you see a circle labeled “Tetrapods 340 Ma”. Click on that. Then answer the following questions: 1. How many species of tetrapods exist today? 2. What are the groups of organisms that form the 2 main branches of Tetrapods? Give 2 examples of each: 1. Branch 1 name and examples: 2. Branch 2 name and examples: 3. Next, locate humans on this tree of life. Clues: fossil evidence indicates humans are related through biological evolution to “Old World” monkeys and apes. Take a screenshot of the example of Homo sapiens shown in the Tree of Life and past it below: 4. Finally, zoom back out and as you do, examine the relationship of humans to mammals to tetrapods to the tree of life as a whole. In the space below, write a paragraph that explains your concept of how fossil evidence can be used to relate 2 different species to one another, using the example of YOUR relationship, as a Homo sapien mammalian tetrapod, to Devonian fish:
