Investigators have long known the gene that controls the hormone vasopressin is responsible for monogamy in prairie voles, small animals common in the grasslands of North America. 研究人員很早就知道，這種基因不僅控制抗利尿激素，也能使草原田鼠這種北美草原常見(jiàn)的小動(dòng)物保持一夫一妻。
Virtually all vertebrates have an oxytocin-like nonapeptide hormone that supports reproductive functions and a vasopressin-like nonapeptide hormone involved in water regulation. 事實(shí)上所有脊椎動(dòng)物都有有利于生殖功能的類(lèi)似催產(chǎn)素的激素，以及水平衡的類(lèi)似于抗利尿激素的激素。
