一项新的研究显示,受到拥挤生活环境压力的怀孕中的母亲会在无意之中不断地为她们的后代作好取得成功的准备。母亲的影响可为其尚未出生的孩子针对出生以后可能会面临的情况作好准备。然而,迄今为止,人们对涉及这一过程的信号和机制还知之甚少。在一个为期22年的红松鼠研究中,Dantzer及其同事在红松鼠数量波动很高的年份中观察到了红松鼠后代的快速生长率。快的 A new study shows that pregnant mothers under pressure from a crowded environment are unknowingly preparing for the success of their offspring. The influence of the mother may prepare her unborn child for what may happen after birth. However, so far, little is known about the signals and mechanisms involved in this process. In a 22-year-old red squirrel study, Dantzer and colleagues observed the rapid growth rate of the offspring of red squirrels in years of high variability in red squirrels. Fast
