行为表型特征或“动物个性”驱动着关键的进化过程，如健康，疾病和信息传播。然而，行为特征的稳定性，从定义上来说是必不可少的，很少在发育的重要时期内进行测量，限制了我们对行为稳定性如何与个体发育相互作用的理解。基于32年的社会行为数据的179野生海豚，我们表明，社会特征（副数量，时间单独和大群体）是稳定的，从婴儿期到成年后期。多变量分析揭示了个体内这些稳定指标之间的密切关系，这表明一种与人类外向性相当的复杂行为综合征。母体效应（特别是垂直社会学习）和性别特异性生殖策略可能是这些模式的直接和最终驱动因素。我们提供了罕见的经验证据来证明社会行为特征在非人类动物中持续数十年。Taylor Evans等人根据对西澳大利亚州的湾海豚社会行为的32年观察结果进行了分析。他们的研究结果表明，个人的社会特征，如偏好独处与群体，在个人的一生中保持稳定，尽管成年后的生理和社会变化。
Behavioral phenotypic traits or “animal personalities” drive critical evolutionary processes such as fitness, disease and information spread. Yet the stability of behavioral traits, essential by definition, has rarely been measured over developmentally significant periods of time, limiting our understanding of how behavioral stability interacts with ontogeny. Based on 32 years of social behavioral data for 179 wild bottlenose dolphins, we show that social traits (associate number, time alone and in large groups) are stable from infancy to late adulthood. Multivariate analysis revealed strong relationships between these stable metrics within individuals, suggesting a complex behavioral syndrome comparable to human extraversion. Maternal effects (particularly vertical social learning) and sex-specific reproductive strategies are likely proximate and ultimate drivers for these patterns. We provide rare empirical evidence to demonstrate the persistence of social behavioral traits over decades in a non-human animal. Taylor Evans et al. present analyses based on 32 years of observations of dolphin social behaviour in Shark Bay, Western Australia. Their findings indicate that individual social traits, such as preference for time spent alone vs in groups, remain stable throughout an individual’s lifetime, despite physiological and social changes through adulthood.
