Recent theory and data suggest that adaptive use of learning in the context of sexual behaviour could contribute to assortative mating. Experiments examining this issue indicated that male Drosophila persimilis that experienced courtship and rejection by heterospecific females exhibited significantly lower levels of heterospecific courtship and mating compared with those of inexperienced males. These results indicate that experience in the context of sexual behaviour in fruit flies could reduce gene flow between diverging populations, which may contribute to incipient speciation.
近期的理论和数据表明,性行为背景下学习的适应性运用可能有助于选型交配。研究这一问题的实验表明,与未经历过求偶的雄性果蝇相比,经历过异种雌性果蝇求偶和拒绝的拟果蝇雄性对异种果蝇的求偶和交配水平显著降低。这些结果表明,果蝇性行为背景下的经历可能会减少分化种群间的基因流动,这可能有助于物种的初步形成。
