Comparing DNA of Rodent and Human Genes
1. In the
DNA clock , some nucleotide changes cause amino acid substitutions
in the encoded protein (nonsynonymous changes), and others do not (synonymous
changes). In a comparison of rodent and human genes, rodents were found to
accumulate synonymous changes 2.0 times faster than humans and nonsynonymous
substitutions 1.3 times as fast. What factors could explain this difference?
How do such data complicate the use of molecular clocks in absolute dating?

2. Imagine
that Pangea were re-formed today. What might be some of the environmental
effects, and how might these changes influence life on Earth?
