Cоnsider the figure belоw. This wоrk comes from some experiments with а tunicаte in the very eаrly stages of embryology. It is considered some of the most meticulous work in embryology that has ever been done, but it depended upon a very special set of circumstances that were not possible in other organisms. What does this figure represent (name it) and what is the importance of it with relation to understanding developmental biology? (2 points) What were the natural aspects of tunicate embryos that made this possible many years ago? (2 points) It is now possible to derive maps of this sort from organisms other than tunicates. List and briefly describe 3 different methods by which this type of analysis can be performed in other organisms that may not have the same natural, advantageous characteristics as the tunicate.
