This unique resource presents 27 laboratory exercises for use in student practical classes, all of which are classic experiments in developmental biology. These are experiments that provided key insights into developmental questions, and many of them are described by the scientists who carried out the original pioneering research. This book provides a bridge between state-of-the-art experimental work and the laboratory classes taken at the undergraduate and post-graduate levels. All chapters follow the same logical format, taking the students from materials and methods, through results and discussion, so that they learn the underlying rationale employed in the research.
