A Caldecott classic celebrating twenty years in print.
David Wiesner received the 1991 Caldecott Medal for Tuesday. In the years that followed, he went on to receive two more Caldecotts, and Tuesday went on to sell half a million copies in the United States and to be published in a dozen foreign countries. Now, with remarkable advances in the technology of color reproduction, the original artwork for Tuesday is being reproduced anew, for an edition even more faithful to the palette and texture of David Wiesner’s watercolor paintings. The whimsical account of a Tuesday when frogs were airborne on their lily pads will continue to enchant readers of all ages.
Assisted reproduction challenges and reinforces traditional understandings of family, kinship and identity. Sperm, egg and embryo donation and surrogacy raise questions about relatedness for parents, children and others involved in creating and raising a child. How socially, morally or psychologically significant is a genetic link between a donor-conceived child and their donor? What should children born through assisted reproduction be told about their origins? Does it matter if a parent is genetically unrelated to their child?
Covering a wide range of topics on snake reproduction and phylogeny, this comprehensive book discusses everything from primordial germ migration in developing embryos to semelparity (death after reproduction) in the aspic viper.
