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 Tyler's Vade Mecum-are referenced throughout the book, and several other valuable new elements have been added.


　Additional updates include:
　　　ㆍ　An increased emphasis on stem cells, which are covered extensively and early in the book.
　　　ㆍ　Sex determination and gametogenesis, instead of being near the end of the volume, are up front, prior to fertilization.
　　　ㆍ　Greatly expanded coverage of neural development, comprising a unit unto itself.
　　　ㆍ　Coverage of new experiments on morphogenesis and differentiation, as well as new techniques such as CRISPR.
