Emphasis was placed on endocrine regulation of the specialized cells that populate these mucosal tissues.展开更多

By 500 Mya, RAG gene evolution had occurred, founding adaptive immunity.The first mammals appeared much later (220 Mya) and reproduced by laying of eggs. Placental mammals with internal gestations and live born offspring have existed for only 100 Mya, with humans and mice being relatively recent mam- malian evolutions.展开更多
