Question

some flowering plants are pollinated by honeybees. at some time in the past, honeybees evolved the ability to see ultraviolet radiation. some flowers have evolved to produce ultraviolet markers on their petals that direct honeybees to the reproductive parts of the flower. what is this an example of?
mutualism
commensalism
predation
coevolution

Explanation:

1. Analyze each option:

• Mutualism: A symbiotic relationship where both species benefit, but this question focuses on evolutionary changes over time between two species, not just the current beneficial relationship.
• Commensalism: One species benefits and the other is unaffected, which does not fit here as both the flower and the honeybee have evolved changes related to each other.
• Predation: One species hunts and eats another, which is not the case here (honeybees are not preying on flowers, and flowers are not preying on honeybees).
• Coevolution: The process by which two or more species evolve in response to each other. Here, honeybees evolved the ability to see UV radiation, and flowers evolved UV markers to direct honeybees, showing reciprocal evolutionary changes.

Answer:

D. coevolution
