为婴儿提供营养来源的母婴二元体的进化对于哺乳动物的起源和随后的多样化至关重要。尽管这对关系很重要，但对母婴功能的研究通常是独立对待的。我们的目标是综合母婴功能方面的工作，讨论我们自己的哺乳研究，并比较哺乳和哺乳的起源及其随后的多样化。我们的中心前提是，虽然大量的工作已经证明了哺乳动物在该系统的母性方面存在差异，但很少有人致力于解决这与婴儿功能的关系。我们首先讨论母亲和婴儿的基本解剖学和生理学。接下来我们讨论乳腺和乳汁以及婴儿哺乳的起源，这与它们随后的多样化不同。然后我们讨论母体和婴儿功能的多样化，强调母体功能（解剖学和生理学）中存在的进化多样性，然后认为婴儿功能的多样性尚未被探索，需要在未来更好地研究。最后，我们讨论了我们理解中的一些漏洞，以及可以解决这些漏洞的未来工作建议。本文是主题“食品加工和动物营养同化”的一部分。
The evolution of the mother/infant dyad providing a source of nutrition for infants is essential for the origin and subsequent diversification of mammals. Despite the importance of this dyad, research on maternal and infant function is often treated independently. Our goal is to synthesize the work on maternal and infant function, discuss our own studies of suckling, and compare the origins of lactation and suckling with their ensuing diversification. Our central premise is that while extensive work has demonstrated variation across mammals in the maternal aspect of this system, very little has been done to address how this relates to infant function. We start with a discussion of the fundamental anatomy and physiology of both mother and infant. We next discuss theoriginof mammary glands and milk, and infant suckling, which is distinct from their subsequentdiversification.We then discuss the diversification of maternal and infant function, highlighting the evolutionary diversity present in maternal function (both anatomically and physiologically), before arguing that the diversity of infant function is unexplored, and needs to be better studied in the future. We end by discussing some of the holes in our understanding, and suggestions for future work that can address these lacunae.This article is part of the theme issue ‘Food processing and nutritional assimilation in animals’.
