Evolution of human maternal investment strategies is hypothesized to be tied to biological constraints and environmental cues. It is likely, however, that the socioecological context in which mothers' decisions are made is equally important. Yet, a lack of studies examining maternal investment from a cross‐cultural, holistic approach has hindered our ability to investigate the evolution of maternal investment strategies. Here, we take a systems‐level approach to study how human life history characteristics, environments, and socioecology influence maternal investment in their children.

婴儿的生活史和社会生态学。

据推测，人类孕产妇投资策略的演变与生物学的限制和环境的线索有关。但是，做出母亲决定的社会生态环境可能同样重要。然而，缺乏跨文化，整体的方法来检验孕产妇投资的研究阻碍了我们调查孕产妇投资策略演变的能力。在这里，我们采用系统级的方法来研究人类生活史特征，环境和社会生态学如何影响母亲对子女的投资。
