Notas del editor
The Problem. We have some exquisite fossil embryo material from the Ediacaran and the Cambrian. The embryos are contemporaneous with the Cambrian explosion, and the emergence of body plans and Phyla. These problems can now be discussed from an embryological perspective. Minor changes in developmental processes can have major results on the morphology of an organism.
