Document Summary

Multiple choice 21 questions: which of the following trees shows a different relationship between organisms 1-8, b. 1 4 5 3 2 8 6 7 4 5 1 2 3 8 7 6: d. 8 7 6 3 2 4 5 1 1 5 4 7 6 8 2 3: none of the above. For questions 2 3 use the phylogenetic tree below to answer the questions. Reason: convergent evolution is when a trait is evolved between organisms and was not originally in their most recent common ancestor. Dna sequences, statistically, can be at most 75% different from the original sequence. The rate of dna mutation, among specific sequences, appears constant: i, ii, i, iii, iii, ii, i, iii, ii. Reason: these statements are all true, but not all of them support the question being asked. I is true and relevant because we have to compare our clock to all organisms.
