1. Consider the phylogenetic tree shown below. Nodes are labeled with numbers (1-13) above each node. You can refer to monophyletic groups (clades) by their ancestral nodes in your answers.

Justify your answer. b) Identify a monophyletic group of your choice that includes choanoflagellates. List all of the members of this group and the node of the common ancestor. c) Which node represents the most recent common ancestor of land plants and animals?

1. Consider the phylogenetic tree shown below. Nodes are labeled with numbers (1-13) above each node. You can refer to monophyletic groups (clades) by their ancestral nodes in your answers. Collagen Extracellular matrix 13 Tight Junctions Single flagellum Insertion in EF1a gene Nucleus Cytoskeleton Organelles 10 11 8 4 Vertebrates -Insects Sponges * Choanoflagellates Capsaspora Fungi * Fonticula * Nuclearia Breviatea Animals Slime molds Shelled amoebae Amoeba Land plants Archaea Bacteria Opisthokonts Eukaryotes *multicellular lineage a) Is the group composed only of Fungi and Fonticula monophyletic? Justify your answer. b) Identify a monophyletic group of your choice that includes choanoflagellates. List all of the members of this group and the node of the common ancestor. c) Which node represents the most recent common ancestor of land plants and animals? d) Assume that multicellularity can be gained but not lost. According to this tree, how many times has multicellularity evolved within eukaryotes? On the tree, mark all branches where multicellularity arose with a star. e) A new species is discovered that has an insertion in the EF la gene and a single flagellum. This new species is multicellular, but does not have collagen or extracellular matrix. What lineage or clade might this new species belong to? Justify your answer. 2
