社会性，作为一种生活史特征，应该与高寿命相关，因为复杂的社会性的特点是生殖抑制，延迟繁殖，增加照顾和生存，其中一些特征选择高寿命。我们研究了合作的父母照顾（代理复杂的社会性）和相对最大寿命在257个北美鸟类之间的关系。在控制了由体重、采样努力、纬度、死亡率、迁移距离和首次繁殖年龄解释的最大寿命变化后，我们在分析物种特异性数据或遗传学独立的标准化线性对比时，没有发现合作护理对寿命的显著影响。因此，社会性本身与长寿无关。相反，长寿与身体大小的增加，存活率和第一次繁殖的年龄有关。
Sociality, as a life-history trait, should be associated with high longevity because complex sociality is characterized by reproductive suppression, delayed breeding, increased care and survival, and some of these traits select for high longevity. We studied the relationship between cooperative parental care (a proxy of complex sociality) and relative maximum lifespan in 257 North American bird species. After controlling for variation in maximum lifespan explained by body mass, sampling effort, latitude, mortality rate, migration distance and age at first reproduction, we found no significant effect of cooperative care on longevity in analyses of species-specific data or phylogenetically independent standardized linear contrasts. Thus, sociality itself is not associated with high longevity. Rather, longevity is correlated with increased body size, survival rate and age of first reproduction.
