Published by Sinauer Associates, an imprint of Oxford University Press. 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.
