Geared for undergraduates, this embryology tutorial leads students step by step through the early, hectic stages of development, when the animal's basic body plan starts to take shape. One section focuses on amphibians, highlighting milestones from egg formation and fertilization to neurulation, when two ridges of tissue curl together along the back to form the spinal cord. The second part probes fertilization and development in sea urchins. A third tutorial on the zebrafish is under construction. Creator Jeffrey Hardin of the University of Wisconsin, Madison, bolsters the text with films and animations.
