Show transcribed image text Reading phylogenetic trees can be difficult and are easy to misinterpret. Read this article from Nature Education: Reading a Phylogenetic Tree: The Meaning of Monophyletic Groups. 1. In this article and in your own words, what is the importance of reproductive isolation? Look at figure 8, at the bottom of the article. In this figure, 'x' and 'y' represent nodes. 2. In your own words, what is a node, and what do 'x' and y represent? 3. According to the tree shown here, does node V' occur before node 'x' in time? Explain your answer. 4. A tree is a representation of a hypothesis of the ancestry of species, proteins, or genes that are being studied. Below are two trees based on figure 8. Are the two trees equivalent and illustrating the same common ancestry of the items labeled A-E? Justify your answer.
