Which statement accurately describes proximate triggers and hormonal influences on mating behavior?

• A. Proximate triggers are long-term evolutionary explanations
• B. Proximate triggers are immediate cues that activate neural circuits; hormones modulate long-term mating motivation and receptivity
• C. Hormones have no effect on mating behavior
• D. Proximate triggers are solely genetic predispositions

Answer: (B)

Proximate triggers are the immediate, mechanistic causes of mating behavior: cues in the environment or internal state that directly activate the neural circuits controlling mating. Hormones act as modulators, shaping how strongly an animal is motivated to mate and how receptive it is, influencing these behaviors over both short-term and longer-term timescales. This description fits because it explains the immediate brain mechanisms behind mating and the hormonal adjustments that tune motivation and receptivity. Other statements mislabel proximate triggers as long-term evolutionary explanations, deny hormonal effects, or view proximate triggers as purely genetic predispositions, which misses the dynamic, brain-based mechanism at work.
