Abstract

Uchiyama et al. emphasize that culture evolves directionally and differentially as a function of selective pressures in different populations. Extending these principles to the level of families, lineages, and individuals exposes additional challenges to estimating heritability. Cultural traits expressed as a function of the genetics whose influence they mask or unmask render inseparable the influences of culture and genetics.

摘要

内山等人强调，文化作为不同人群中选择压力的函数，会朝着特定的方向进化，并呈现出差异。将这些原则扩展到家庭、谱系和个体层面，会给遗传力的估计带来更多挑战。作为遗传影响的表现形式的文化特征，掩盖或揭示了遗传的影响，从而使文化和遗传的影响变得不可分割。
