7. Consider the evolution of land plants. a. According to the phylogeny of land plants, pores are an ancestral trait and stomata are derived. Explain why this is logical, in terms of the mutations that had to occur for these traits to evolve. (2 sentences max) (2 pts) b. Despite the advantages of stomata, Liverworts still thrive today and only have pores. Why? (2 sentences max) (2 pts)

Constructing a phylogeny Imagine a scenario with 3 species plus an ancestral sequence, and data consisting of a nucleotide sequence only 4 bases in length. 1. Draw a diagram for all possible phylogenetic arrangements of these three species and their known group. 2. On each phylogeny, CLEARLY indicate where and in what way there must have been a change in character state for each position in the nucleotide sequence.
