The chicken embryo is a unique model that overcomes many limitations to studying the biology of cancer in vivo. The chorioallantoic membrane (CAM), a well-vascularized extra-embryonic tissue located underneath the eggshell, has a successful history as a biological platform for the molecular analysis of cancer including viral oncogenesis, [8] carcinogenesis, [9] tumor xenografting, [1] [10] [11 ...
Domestication. Dogs and sheep were among the first animals to be domesticated, at least 15,000 and 11,000 years ago respectively. [ 1] Rice was domesticated in China, some 9,000 years ago.
