In the table below is a short gene sequence in 4 closely related taxa and an outgroup. 1. Based on comparisons of this DNA sequence, determine the placement of these four taxa in the phylogenetic tree below. Clearly identify the taxon (P, Q, R, or S) that corresponds to each branch tip (1, 2, 3, or 4). 2. Based on your constructed tree, is Species P more closely related to Species Q or Species S? Justify your answer. Nucleotide Position 1 2 3 4 5 6 7 8 Outgroup G C Taxon P C A C T Taxon Q Taxon R A A C Таxon S A A T
