Independent of ecology, subsistence strategy, social complexity, or other aspects of socioecology, the altricial nature of young humans requires mothers to have help raising their offspring. What seems to be context-dependent, however, is who the helpers are, how they invest, and what the impacts of that investment are. In a series of papers that focus on parental and alloparental investment across five populations, this special issue of Human Nature uses evolutionary theory to examine how socioecological context influences modes of direct parental investment among the boat-dwelling Shodagor of Bangladesh (Starkweather), modes of indirect paternal investment in the modern United States (Anderson), and the biological outcome of paternal investment for men in Jamaica (Gray et al.), as well as direct alloparental investment among village Bangladeshis (Perry) and indirect alloparental investment in breastfeeding practices in the United States (Cisco).
不论生态环境、生存策略、社会复杂性或社会生态学的其他方面如何，人类幼崽的早产特性都需要母亲在养育后代时得到帮助。然而，帮手是谁、他们如何投入以及这种投入会产生什么影响，似乎取决于具体情境。在一系列聚焦于五个群体中亲代和异亲投资的论文中，《人性》这一特刊运用进化理论，考察了社会生态环境如何影响孟加拉国以船为家的绍达戈尔人（斯塔克韦瑟）的直接亲代投资模式、现代美国的间接父代投资模式（安德森）、牙买加男性父代投资的生物学结果（格雷等人），以及孟加拉国村民的直接异亲投资（佩里）和美国母乳喂养实践中的间接异亲投资（思科）。
