在秘鲁南部高地的一个社会经济条件差的群体（“Barriada”）中，研究了亲本体型变化与后代存活率的关系。小体型的父母，特别是母亲，有显着更大的百分比后代存活率比父母与较大的身体尺寸。换句话说，小体型个体的后代存活效率大于大体型个体。据推测，与较小的亲本体型相关的更大的后代生存效率可能反映了对不良社会经济条件的适应性反应。
The relationship of variations in parental body size to offspring survival has been studied in a population of poor socio‐economic conditions (“Barriada”) in the southern highland of Peru. Parents of small body size, especially mothers, had significantly greater per cent offspring survival than parents with larger body size. In other words, the offspring survival effectiveness of subjects of small body size was greater than that of subjects of large body size. It is postulated that the greater offspring survival effectiveness associated with small parental body size may reflect possible adaptive responses to poor socio‐economic conditions.
