动物行为的巨大多样性激发了来自一系列生物学科的几代科学家。为了补充对行为进化的生态和进化因素的研究，现代计算，遗传学，基因组学和神经科学工具现在提供了一种手段来发现自然选择产生行为多样性的近似机制。社会行为是有动机的行为，在密切相关的物种之间可能存在巨大差异，这表明它们潜在的生物学机制具有系统发育可塑性。此外，趋同进化一再在远亲物种中产生类似形式的社会行为和交配系统。社会行为的分歧和收敛提供了一个切入点，了解神经遗传机制，有助于行为的多样性。我们认为，在理解社会行为多样性的最大进步将通过整合跨学科的比较方法与现代工具，在不同的物种系统。我们回顾最近的进展和未来的潜力，发现机制的社会行为的变化，突出模式的社会行为进化，催产素和加压素神经肽系统，遗传/转录“工具包”，现代技术，和替代物种系统，特别强调Microtine啮齿动物和马拉维湖慈鲷鱼。
The tremendous diversity of animal behaviors has inspired generations of scientists from an array of biological disciplines. To complement investigations of ecological and evolutionary factors contributing to behavioral evolution, modern computational, genetics, genomics, and neuroscience tools now provide a means to discover the proximate mechanisms upon which natural selection acts to generate behavioral diversity. Social behaviors are motivated behaviors that can differ tremendously between closely related species, suggesting phylogenetic plasticity in their underlying biological mechanisms. Additionally, convergent evolution has repeatedly given rise to similar forms of social behavior and mating systems in distantly related species. Social behavioral divergence and convergence provides an entry point for understanding the neurogenetic mechanisms contributing to behavioral diversity. We argue that the greatest strides in understanding social behavioral diversity will be achieved through integration of interdisciplinary comparative approaches with modern tools in diverse species systems. We review recent advances and future potential for discovering mechanisms underlying social behavioral variation, highlighting patterns of social behavioral evolution, oxytocin and vasopressin neuropeptide systems, genetic/transcriptional “toolkits,” modern techniques, and alternative species systems, with particular emphasis on Microtine rodents and Lake Malawi cichlid fishes.
