Divergence Time Estimates Based on Molecular Clocks Are

question 14

Multiple Choice

Divergence time estimates based on molecular clocks are

• A)likely to be correct plus or minus a few decades.
• B)more reliable than divergence dates that are based on analysis of the fossil record.
• C)best interpreted with caution,since they depend on assumptions that are difficult to test.
• D)usually worthless since we cannot directly observe divergence times unless we invent a time machine.
