Unformatted text preview: (If specilization on particular host plants is a reason that some lineages of insects have more species than others, could predation by birds also be a reason?) On Question #34, I understood there were at least two mutations (Glu-Asp and Phe-Leu) but how do we know if they are synonymous or non-synonymous. I chose D. We cannot infer the mutational history of a gene given a protein sequence but the answer is A. There have been at least 2 mutations that resulted in non-synonymous substitutions. 34. Examining the amino acid sequence of a protein foundin 2 closely related species of bats we find: Species 1: Ala-Glu-His-Cys-Phe-Leu-Tyr Species 2: Ala-Asp-His-Cyc-Leu-Leu-Tyr Assuming that we have aligned the sequences properly, what can we say about the accumulation of mutations since these species diverged from the common ancestor?...
