1. How might similarities and differences in genetic codes, or the proteins built as a result of these codes, be used to determine how closely related different species are? 2. Based on the amino acid sequence data, what species do humans appear to be most closely related to and most distantly related to? Explain your answer. 3. How does a universal genetic code relate to the hypotheses about the origin of life on Earth? 4. How are self-replicating molecules, such as RNA molecules in the “RNA World” hypothesis, essential to the most popular hypotheses about the origin of life on Earth? Sum1.
