Abstract

To find a suitable mate, many animals across taxa use social information. Mate copying is a form of social learning in which individuals use information regarding potential mates by observing and copying the mate choices of other individuals. While mate copying in Drosophila melanogaster has been extensively documented in the laboratory and its potential for cultural evolution has been demonstrated, little is known about mate copying in other Drosophila species. Here, we report the first evidence that Drosophila simulans females also copy the mate choice of their conspecifics. We used the well-established protocol developed for D. melanogaster: a naive, unmated female first observes a conspecific's mate choice between one artificially coloured green and one artificially coloured pink male and is afterwards allowed to choose between two males of the same phenotypes herself. Just as with D. melanogaster, D. simulans females were more likely to choose the same type of male as in the demonstration. This finding underscores the capacity of D. simulans females to engage in rapid social observational learning, a process that may play a significant role in the evolution of reproductive isolation.

拟果蝇的配偶复制。
为了寻找合适的配偶,许多动物利用社会信息。配偶复制是一种社会学习的形式,个体通过观察和复制其他个体的配偶选择来使用有关潜在配偶的信息。虽然黑腹果蝇(Drosophila melanogaster)的配偶复制已经在实验室中得到了广泛的记录,其文化进化的潜力也得到了证明,但对其他果蝇物种的配偶复制知之甚少。在这里,我们报告了第一个证据,证明拟果蝇的雌性也会复制它们同种的配偶选择。我们采用了一种成熟的方法来研究黑腹龙眼:一只幼稚的、未交配的雌性首先观察一只同种龙眼在一只人工染成绿色和一只人工染成粉红色的雄性龙眼之间的配偶选择,然后允许雌性龙眼在两只具有相同表型的雄性龙眼之间进行选择。就像黑腹d.m anogaster一样,雌性D. simulans更有可能选择与演示中相同类型的雄性。这一发现强调了D. simulans雌性参与快速社会观察学习的能力,这一过程可能在生殖隔离的进化中发挥了重要作用。

期刊介绍: Previously a supplement to Proceedings B, and launched as an independent journal in 2005, Biology Letters is a primarily online, peer-reviewed journal that publishes short, high-quality articles, reviews and opinion pieces from across the biological sciences. The scope of Biology Letters is vast - publishing high-quality research in any area of the biological sciences. However, we have particular strengths in the biology, evolution and ecology of whole organisms. We also publish in other areas of biology, such as molecular ecology and evolution, environmental science, and phylogenetics.
