LR Question 18 Explanation

QUESTION TEXT: While it is true that bees’ vision is well suited to the task…

QUESTION TYPE: Strengthen

CONCLUSION: Flowers evolved to match the vision of bees, rather than the other way around.

ANALYSIS: Bees need flowers, flowers need bees. We’re told bees see in color, and flowers are colorful. So did bees learn to see color to find flowers, or did flowers become colorful to attract bees?

The stimulus argues that flowers evolved color to help them attract bees. There are at least two possible answers which could help strengthen the conclusion:

Something which indicates flowers evolved color to help them attract bees.

Something which indicates bees’ vision did not evolve so that they could see flowers.

___________

1. CORRECT. If other insects have similar vision but don’t need to see in color, then perhaps bees did not need to see in color when they first evolved their vision. This strengthens the idea that flowers evolved color to adapt to the vision of bees.
2. Since we’re arguing that flowers depend on bees, this weakens the argument.
3. The number of species doesn’t matter; we’re simply concerned about their relationship.
4. This doesn’t tell us anything about what flowering plants do. Not helpful.
5. This may be true of present day bees, but we’re concerned about how bees and flowers evolved their color and vision in the past.
