A classic gets a new coauthor and a new approach: Developmental Biology, Eleventh Edition, keeps the excellent writing, accuracy, and enthusiasm of the Gilbert Developmental Biology book, streamlines it, adds innovative electronic supplements, and creates a new textbook for those teaching Developmental Biology to a new generation. Several new modes of teaching are employed in the new Gilbert and Barresi textbook. The videos explaining development--as well as those from Mary Tylers Vade Mecum--are referenced throughout the book, and several other valuable new elements have been added.

　　* Greatly expanded coverage of neural development, comprising a unit unto itself.

　　* Coverage of new experiments on morphogenesis and differentiation, as well as new techniques such as CRISPR.
