Contents: How, when and why did epigenetic silencing evolve in mammals? -- examination of two mammal-specific systems, genomic imprinting and X-chromosome inactivation, from an evolutionary standpoint, using comparisons between humans, distantly related mammals (marsupials and monotremes) and other vertebrates -- independent evolution of imprinting in different genomic regions and correlation with evolution of viviparity -- step-wise evolution of the elements of the complex X-chromosome inactivation mechanism -- shared features of imprinting and X-inactivation.
