Discuss the following tree with your  teammates. If you hover over the pink hexagon with three dots it will give you more upload options - one of these is the DRAW tool. At the end of the slide series, the Team Leader should post a drawing of the final tree.

Draw a branching tree for the following taxa:

Archaea, Cyanobacteria,  Proteobacteria, Paulinella, Opisthokonts, and Plants.

Draw arrows indicating the contribution of cyanobacteria and  proteobacteria to other organisms on your tree. Use a separate arrow for  each evolutionary event (hint: sometimes the arrow may go to a node rather than a branch).
