The available evidence indicates that a biological clock oscillates in the mammalian fetus and that the fetal clock is entrained by redundant circadian signals from the mother. An entrainable biological clock during fetal life helps the developing mammal more readily prepare for life in the outside world. In humans, the early establishment of maternal-infant synchrony may help the infant maximize its responsiveness to the outside world.
现有证据表明，生物钟在哺乳动物胎儿体内振荡，并且胎儿生物钟受来自母体的冗余昼夜节律信号的影响。胎儿期可被影响的生物钟有助于发育中的哺乳动物更轻松地为外界生活做好准备。在人类中，母婴同步性的早期建立可能有助于婴儿最大限度地提高对外界的反应能力。
