During a field trip, an instructor touched a moth resting on a tree trunk. The moth raised its forewings to reveal large eyespots on its hind wings. The instructor asked why the moth lifted its wings. One student answered that sensory receptors had fired and triggered a neuronal reflex culminating in the contraction of certain muscles. A second student responded that the behavior might frighten predators. Which statement best describes these explanations?

A) The first explanation is correct, but the second is incorrect.
B) The first explanation refers to proximate causation, whereas the second refers to ultimate causation.
C) The first explanation is biological, whereas the second is philosophical.
D) The first explanation is testable as a scientific hypothesis, whereas the second is not.
E) Both explanations are reasonable and simply represent a difference of opinion.

A second student responded that the behavior might frighten predators. Which statement best describes these explanations? B) The first explanation refers to proximate causation, whereas the second refers to ultimate causation.

Explanation:

The proximate causation is the immediately responsible for causing, but the ultimate causation is the actual real cause. The sensory receptors that trigger a neuronal reflex culminating in the contraction of muscles is definitely the proximate causation. If we go further, the ultimate causation is what the second student said: the behavior might frighten predators
