Abstract：
BACKGROUND: The Evolved Developmental Niche (EDN) is a millions-year-old developmental system that matches the maturational schedule of the offspring, optimizing health. Every animal has a developmental niche.
OBJECTIVE: Humanity has fallen away from providing its EDN. Does it matter?
METHODS: Several components of humanity\'s EDN were reviewed (breastfeeding, positive touch, allomothers, responsive care, free play) in relation to cardiac vagal nerve regulation, a signal of healthy development. Focal subjects were young children.
METHODS: A review of research on the selected EDN components in relation to vagal nerve function was performed. Data were available for all but the allomother component, which is typically not measured by western researchers, although allomothers provide EDN components alongside parents.
RESULTS: Apart from the lack of research on allomother effects, all these EDN components have been shown to influence cardiac vagal regulation in young children.
CONCLUSIONS: Converging evidence suggests that providing the EDN in early life may not only support aspects of a child\'s primal health system, but bolster capacities for social health and wellness, the cornerstone of a positive life trajectory.

摘要：
背景：进化发育小生境（EDN）是一个具有数百万年历史的发育系统，与后代的成熟时间表相匹配，优化健康。每一种动物都有发展的生态位。
目标：人类已经远离提供EDN。重要吗？
方法：回顾了人类EDN的几个组成部分（母乳喂养，积极的触摸，allomothers,反应灵敏的护理，自由发挥)与心脏迷走神经调节有关，健康发展的信号。焦点对象是幼儿。
方法：对所选EDN成分与迷走神经功能相关的研究进行了综述。除了其他组件之外，所有组件的数据都可用，这通常是西方研究人员无法测量的，尽管alomothers与父母一起提供EDN组件。
结果：除了缺乏对其他效应的研究外，所有这些EDN成分已被证明会影响幼儿的心脏迷走神经调节。
结论：融合的证据表明，在早年提供EDN可能不仅支持儿童的原始健康系统的各个方面，但是增强社会健康和保健的能力，积极生活轨迹的基石。
