Human biological variation in the phenotype is the cornerstone of modern human biology, evolutionary anthropology, and related studies of human evolution. Minimal dialogue, however, has considered human milk to be part of this phenotypic variation. This may reflect researcher bias‐mental models oriented around commercial infant formula and homogenized cow's milk, both of which present milk composition as static. A general lack of research outside primarily Western, well‐nourished populations has also contributed to this underestimation of biological variation.

将母乳成分作为正常的人类生物学变异

人类生物表型变异是现代人类生物学、进化人类学和人类进化相关研究的基石。然而，最少的对话认为母乳是这种表型变异的一部分。这可能反映了研究人员偏向于以商业婴儿配方奶粉和均质牛奶为导向的心理模型，两者都将牛奶成分呈现为静态。除了主要是西方、营养良好的人群之外，普遍缺乏研究也导致了这种对生物变异的低估。
