Divergence Time Estimates Based on Molecular Clocks Are

question 72

Multiple Choice

Divergence time estimates based on molecular clocks are

• A) best interpreted with caution, since they depend on assumptions that are difficult to test.
• B) likely to be correct regardless of the genes used or the groups of organisms.
• C) more reliable than divergence dates that are based on analysis of the fossil record.

Describe the role of specific plant groups in the history of Earth, such as their contribution to coal deposits.

Understand the impact of structural and reproductive adaptations on plant diversity and evolution.

Identify the structures characteristic of vascular plants and their significance.
