Fоr this questiоn, yоu mаy wаnt to drаw your own tree using the species and traits clues below and then answer the question.Ichthyostega is a 370-million-year-old fossil from Greenland. Ichthyostega had digits, eyes on the top of its head, and strong, armlike bones. It also had no gills and a reduced tail—traits it had in common with Tulerpeton. Acanthostega, Eusthenopteron, and Tiktaalik all had gills and full tails. If we give each species and trait an acronym, we might get something like this:Species:A = Acanthostega E = Eusthenopteron I = IchthyostegaTu = TulerpetonTi = Tiktaalik Traits: D = digits E = eyes on top of a flat head G/T = loss of gills and a reduced tail S = strong, armlike bones Now, we can put that information into an evolution tree, which could look like this: To complete this tree, which acronyms would fit into spot 2 (the blue circle) and spot 3 (the green circle)?
