Plasticity in the growth of body segments between populations has been researched in relation to migration, temporal change and high‐altitude studies. We study the within population variation in body segments, thus controlling for some of the environmental and genetic differences that could be at play in between populations studies. We test a version of the thrifty phenotype hypothesis, where the growth of head‐trunk and hand are prioritized due to their functional significance over height and leg growth.

危地马拉与年龄相关的身高和孕产妇教育方面的身体区段增长的可塑性

关于人口迁移，时间变化和高海拔研究，已经研究了人口之间身体部分的可塑性增长。我们研究了人体各部分的内部变异，从而控制了人群研究之间可能发挥的某些环境和遗传差异。我们测试了节俭表型假设的一种版本，其中头尾和手部的生长由于其对身高和腿部生长的功能重要性而被优先考虑。
